shaneo Posted May 26, 2014 Share Posted May 26, 2014 (edited) PhLi i gather is not a grignard reagent. otherwise it would be PhMgLi.I'm wondering if there is a triple bond from Ph to Li because then i will be able to use the Organo metallics with ketone reaction.Even still, i'm not sure how the valency of a phenyl ring would be able to accommodate for the aforementioned bond?The starting material is: cyclohexanone with a c=c bond on the 2nd carbon. Which leads me onto a side question, alkene's don't have prefix names and so what is the name of this molecule?Baring in mind ketone groups have a higher priority in IUPAC naming terms than alkenes. Sorry about my amateur layout.Shane btw the C=C bond is not an R group off of one of the Cyclohexanone carbons. It is part of the ring system Edited May 26, 2014 by shaneo Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted May 26, 2014 Share Posted May 26, 2014 Hexanone indicates an alkane carbon chain with a C=O, so using that same relationship what would you expect the same compound with an alkene group be called? You also need to specify the position of the ene group with a number (as in for example, cyclopent-1-ene). As for the first part, RMgLi is still not a Grignard reagent. At all. Look up organolithium reagents and what they are used for. 1 Link to comment Share on other sites More sharing options...
