Triphenylphosphine reacts with dialkyl acetylenedicarboxylates in the presence of NH-acids, such as benzanilide, 2-cyanobenzanilide, N-(2-acetylphenyl)benzamide, 3-nitrobenzanilide and methyl 2-benzamidobenzoate to generate stable phosphorus ylides. These stable ylides exist in solution as a mixture of two geometrical isomers as a result of restricted rotation around the carbon-carbon partial double bond resulting from conjugation of the ylide moiety with the adjacent carbonyl group.
