Preparation of unsaturated aldehydes from propargyl alcohol and conjugated diolefins

摘要

Unsaturated aldehydes are prepared by mixing propargyl alcohol, a catalyst and a conjugated diolefin and heating the mixture for a time and at a temperature sufficient to form an unsaturated aldehyde. The diolefin may be 2-methylpentadiene, 2(5,5 dimethyl 5 hydroxy pentyl)1,3 butadiene or myrcene. The catalyst may be inorganic, organic, organometallic or mixtures thereof.
