Abstract

Trialkyl(aryl)phonio-alkylids can combine with carbonyl compounds to afford zwitterionic “phosphorus betaines” as detectable intermediates of the Wittig reaction, provided however that the negative charge residing at the oxygen atom is substantially reduced by binding to a lithium cation or by resonance delocalization into an adjacent carbonyl group.
