Abstract

The syntheses of pure cis‐ and trans‐3‐hexenal are described. It is shown that earlier reported preparations of 3‐hexenal or β‐hexenal led in most cases to the isomeric 2‐hexenal.

The authors describe a new general synthesis of cis-,&ethylene aldehydes : the alkylation of 1-methoxy-1-buten-3-yne to 1-methoxy-1-alken-3-ynes followed by addition of methanol produces l,l-dimethoxy-3-alkynes. The catalytical reduction of these compounds to l,l-dimethoxy-3-alkenes followed by mild
