Abstract

The reaction of benzoylmethylenetriphenylphosphorane (I) and -arsorane (II) with RCYCCNC:C2F5, n-C3F7) took place smoothly. At room temperature, Ph3P:C(CN)CR:CHBz were formed from phosphonium ylide I in high yield and mixtures of Ph3As:C(CN)CR:CHBz and Ph3As:CBaCR:CHCN were formed from arsonium ylide II and they could be separated by chromatog. and the total yields were about 95%. At low temperature (-78癈), Ph3M:CBzCR:CHCN (M = P, A5) were formed as the sole products in moderate yield.

Key words: ORGANO PHOSPHORUS COMPOUNDS, BENZENECARBOXYLIC ACID P, TRIPHENYLPHOSPHINE, ALKYNE P, NITRILE, ORGANO ARSENIUM COMPOUNDS, PERFLUORO-HYDROCARBON, YLIDE
