Abstract
Primary alkenols are produced by transesterifying a primary alkenol acetate with methanol in the presence of the hydroxide or alkoxide of a metal in the first to third main group of the Periodic Table as catalyst. Preferably the methanol is present in large excess and the by-product methyl acetate is removed as an azeotrope with the excess methanol. The reaction is preferably effected under anhydrous conditions and it is substantially quantitative.
