Hey all I was wondering what the expected product should be in this reaction, everywhere i looked says it will be the same product as for the base reaction, but I dont think that is right. The product I predicted was having an acyl group on the anhydride substitute for the hydrogen on the aldehyde part of Vanillin. Can anyone tell me if this is correct? thank you.

:DHi every body , how are you ? I hope you are well. please help me Iam in the third year of faculty of science (ALEX UNIVERSTY EGYPT) and the next year which specialize chemistry type and I dont know what will I choose ( organic _ inorganic_....)???? I dont know ??? please help me . thank for all

Okay i need a little help. I have to synthesize http://i39.tinypic.com/send5l.jpg Using a grignard reaction. I have two ideas right now. Let me know what you think. http://i42.tinypic.com/r9jxix.jpg and http://i43.tinypic.com/2z7hegz.jpg Thanks

I'm looking for an efficient way to extract the essential oil from Jasmine flowers. I've discovered a supplier that will provide me with the flowers for a very low cost, and I want to make an essential oil out of them. I know that for Jasmine, because of its fragile molecular nature, a solvent extraction is required. Steam distillation will not work; it will destroy the perfume of the oil. Does anyone know of an efficient solvent extraction method for Jasmine essential oil? Which solvent/s do I use? Thank you!

In my orgo textbook, it says that that one of the most common ways of making alkyl halides is: SN1 rxn with tertiary alcohol However, a halide is a much BETTER leaving group than an OH group...so why does this reaction work? Thanks in advance

Hi, A synthesis my lecturer dubbed 'iodoetherification' cropped up this week. I can't find reference to it or anything much like it in my organic text; can anyone recommend a book or article with a decent explanation of it? Cheers Kaeroll

(Sorry for my English), but about this reaction: Na + CHCl3 -> NaCl + ? + ? Who knows what are the stable products that are formed in addition to NaCl? Those who actually come from the tube! (...dichlorocarbene...if... not stable...!) Thank you

I am a trainee in a company which is producing 2-chloro-4-amino sulfonamide. They start with meta chloro aniline & did chlorosulfonation with CSA (chlorosulfonic acid) followed by SOCl2 (Sulfonyl chloride) & then amination using ammonia. When I referred Vogel, I found that R-H + ClSO3H = R-HSO3 + HCl R-H + 2 ClSO3H = R-SO2Cl + HCl + H2SO4 Where R - is aromatic benzene ring. Since Company is already using 8 times of theoretical value why they are using sulfonyl chloride. The product is formed like this R1-SO2Cl + NH3 = R1-SO2NH2 +HCl Where R1 - is meta chloro aniline radical kind of structure. Can anyone help me. Can I use any…

what's the point of organic chemistry? I mean I see the fun in unorganic chemistry- i.e. creating cool compounds, salts, nice bangs & flashes, etc. but like the things i see people making here- cyclohexylmethanamine, p-nitrobromobenzene, 2-methylcyclohexanone, etc., what's so interesting to do with them? really, the only things i see where organic syntheses are useful are like industrial products (i.e. making hydrocarbons, etc.) and drugs/medicines, but what can you possibly do with the products of the organic experiments you do at home? and if you do make some kind of methylation/nitration or cyclisize or hydrlosize something, how would you know? its not …

Does LiAlH4 react with formaldehyde? If so, what's the product? My book focuses on LiAlH4 reacting with other things but doesn't mention formaldehyde.

I am making my first post in these forums here. I have a question about the chemical THC in it's purest form concerning it's lethal dose. Is there anything safer for the human body to consume other than nitrogen, oxygen and THC?

Hi. I'm on a little project trying to study encapsulation of 2-hydroxybenzoic and 4-hydroxybenzoic acid in alpha and beta-cyclodextrin (CD). The method is to keep constant the concentration of the acid and variate the CD concentration, adding NaCl to keep the ionic strength constant. Right now i'm only doing UV-Vis measurements and i'm having bad results (or bad data treatment). I've attachted some results. Any sugestions? I'm only using the Benesi-Hildbrand Model, the only i found to study encapsulations. I'm feeling a little lost and my teacher don't have much time to dedicate to this project.. Thanks!!! PS - Sorry my bad english.. :S 2HB - aCD.xls.zi…

Hi all, I have a problem interpreting a spectrum I ran recently. It's a simple proton NMR of 2,3-dimethylbutan-1-ol. I don't have access to a scanner so unfortunately I can't post the spectrum here, but a near-identical version is available at sdbs. (Which, by the way, is an excellent resource) If anyone's interested in helping with this problem I recommend accessing it there. Its CAS no is 19550-30-2. I've assigned (hopefully correctly) all peaks other than the peak at 3.5ppm. On my spectrum it appears to be a doublet of quartets, with non-binomial intensities, but I'm not sure. From one end to the other, I see two peaks of roughly equal intensity, two of double …

I was curious if an amine or amide was basic enough to open up an epoxide. I think it can, plus I found this article, but am not sure if am understanding it correctly. Thanks. http://www3.interscience.wiley.com/journal/117906840/abstract?CRETRY=1&SRETRY=0

Hello friends, Can anyone please help me to answer this question? http://www.mypicx.com/uploadimg/745171180_04162009_1.jpg Thank you

I'm supposed to put four compounds in the order of time they will spend on a polar and a non-polar stationary phase in a gas chromatograph. The compounds are a carbon ring with an oxygen, a benzene ring, a cyclohexane, and a compound with a tertiary amine and a ketone. The boiling points are also given, respectively 66, 138, 121, and 166. I can't figure out if I should use just the polarity or somehow also use the BPs. As I understand it, on a polar column, the non-polar compounds would move faster - so cyclohexane is fastest, then benzene, then the ring with an oxygen, and then the amine / ketone compound would be slowest. The reserve would be true on a non-polar st…

Hey all, I need help in reading this data. I had to identify an unknown in organic lab and I have conclusively shown it to be ethyl p-aminobenzoate, but my professor won't accept my conclusion until I derive a molecular formula from the spectra data. I did everything I could just so I wouldnt have to use the spec data. The pics look large, but theyre kinda hard to read. Any direction or hints as to go about this, well, that would be great. Thanks!

Hi guys, first time posting and I am sure I will be a frequent poster as I am really trying to master this subject material. My question is concerning solvolysis with ethanol: If I mix 2-bromo-2-methylbutane with heated ehtanol (which is a protic solvent correct?) I should produce two products correct?.......The ethanol oxygen replacing the bromine molecule attached to the 2nd carbon as well as the hydrogen attached to the oxygen atom being bonded to the displaced bromine atom? I just want to make sure I am understanding all this for Sn2 and Sn1 reactions. Scott

I have generated a Mass Spectrum for PAracetamol extracted from a coproxamol tablet and analysed by GCMS. I see major peaks at m/z 43, 80, 109, 151. 151 is clearly the parent ion and 109 and 43 the fragments formed by the cleavage of the CO-NH bond. but I have no idea where the peak at m/z 80 comes from... can anyone help ? Thanks in Advance A

aka: isopropylphenylacetylene I have an idea how to get this, but it may be wrong or there may be an easier way to get to the product. The guidelines are: may only use benzene, acohols, alkyl halides with 3 carbons or less, and inorganic reagents can be used. I have a feeling there is an easier way since we don't even get into dehydrogenations and Sonogashira couplings in orgo2. This is what I have: 1) Benzene + CH3CH2CL ->ALCL3-> to give ethylbenzene 2) dyhydrogenation performed to give ethenylbenzene 3) addition of Br2 to give (1,2-Dibromoethyl)-benzene 4) NaNH2 in lquid ammonia to give phenyl acetylene 5) Sonogashira Coupling performed with 2-bromo…

Hi, can anyone tell me how to dissolve EDTA with acid and alkaline with the concentration of the reagents also. Thanks.

For the two molecules trans- and cis-Cl(H)C=C(H)Cl, how do i determine whether or not the C-C stretch is infrared active in each case?

I want to get a good grasp of the BASICS of the different functional groups. Does anyone know of any good websites or books that summarize this? For example: which have the highest melting points which are most acidic etc...?
