Acetates of unsaturated primary alcohols were produced when mixtures of unsaturated hydro-carbons and paraformaldehyde were heated in autoclave in the presence of acetic anhydride.
Saponification of these acetates gave the corresponding alcohols.
From α-diisobutylene a mixture of acetate of 3, 5, 5-trimethyl-3-hexene-l-ol and 3-methylene-5, 5 -dimethylhexanol-1, from β-diisobutylene a mixture of acetate of 2, 4, 4-trimethyl-3-oxymethyl-pentene-1 and 3-methylene-5, 5-dimethylhexanol-1 were respectively produced.
Acetic anhydride was more effective solvent than acetic acid in these reactions.
