    Predicting Further Values in a Set of Data

    ! Moderator Note One thread per topic, please.

    CH3OH + 2CuO Which reaction is true?

    I’m not overly familiar with using copper in this way, but I believe that you would typically use CuO catalytically in the presence of O2 (rather than stoicheometrically) to give the aldehyde. I don’t think you would get the acid, but I am not 100% sure.

    Question re Mannich reaction

    1. I am not sure what you want here. Have you encountered a problem in your synthesis? What procedure were you following? 2. I assume you mean spots on a TLC? If you can see two distinct spots you should be able to separate them, provided the difference in Rf is sufficient.

    Chemical reactions

    Is this homework? If so, you’ll need to show some attempt at working out and to detail where exactly you are struggling.

    ! Moderator Note Please note that this is an English speaking forum. We understand language barriers can be difficult to navigate, but our members are fairly accomodating and your history here shows you are able to speak some English. Regardless, I am closing this thread since you already have one open from several years ago. Please post there.

    Diphenyl ether formation

    There are a few ways. Ullman, as you suggested, Buchwald Hartwig coupling, or Chan Lam. Organic portal has an overview of these, plus literature examples. https://www.organic-chemistry.org/synthesis/C1O/biarylethers.shtm

    Diphenyl ether formation

    Are you actually trying to make this?

    Not necessarily; with careful addition and control of equivalents I should think the esters would hydrolyse over the imide. A carbonate base may also do the trick.

    I didn’t say that. I said it can’t be done with an alkoxide. If you do the arrow pushing on the scheme you drew you should hopefully be able to see why it would never work. I also went on to say that in order to do the reaction you need hydroxide or some other aqueous base, but you can also use acid. I think hydroxide base would work fine, however.

    Organic Research Project

    I’d say your main problem is that you can’t hydrolyse the ester with an alkoxide like that. You need a hydroxide, or you need to do it under acidic conditions.

    Exam question.

    Could you show your attempts at solving the question?
