ResumoAbstract 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.
