Resumo

Abstract The products and stereochemistry of the reaction of the benzyltriphenylarsonium ylide with benzaldehyde and acetaldehyde both in the presence of lithium salts and under salt‐free conditions are studied by H NMR at 360 MHz. The stereochemistry is discussed in view of recent developments in the mechanistic interpretation of the Wittig and Johnson‐Corey‐Chaykovsky reaction.
