Ruder, Suzanne M.
, p. 53 - 58 (2007/10/02)
The reaction of ketophosphonium ylides with dimethyl acetylenedicarboxylate in aprotic solvents gave mixtures of Z and E alkene products.Under protic conditions the initial Michael adduct was protonated and gave Z and E isomers of the alkene product as well.Depending on the alkyl group of the ketoylide, different product ratios were seen.Key words: Ketophosphonium ylide, dimethyl acetylenedicarboxylate, rearrangement, Michael addition.
