Abstract

An efficient and convenient procedure for the oxidation of acetylenic alcohols and diols by o-iodoxybenzoic acid (IBX) is reported. Simple heating of the corresponding alcohol with a suspension of IBX in acetone or tetrahydrofuran leads to the silicon(germanium)-containing propynals or γ-hydroxypropynals in high yields.
