1,5-Phosphonium betaines from N-triflylpropiolamides, triphenylphosphane, and active methylene compounds

N-Phenyl-N-(trifluoromethylsulfonyl)propiolamides react with triphenylphosphane in the presence of various active methylene compounds CH(2)XY in a 1:1:1 molar ratio to furnish 1-phosphonium-5-oxabetaines, Ph(3)P(+)–C(R)=CH–C(O(–))=CXY. These betaines are formed preferentially, but not exclusively, a...
