Chemoselective Thioacetalisation and Transthioacetalisation of Aldehydes Catalyzed by PVP‐I

Abstract

Thioacetals of various aldehydes were obtained directly from aldehydes or by a transthioacetalisation process from O,O‐acetals catalyzed by Povidone‐iodine (PVP−I) with good to excellent yields. Attractive features of this method include mild reaction conditions, low catalyst loading, recyclability of catalyst, facile purification of products, and high synthetic efficiency.
