Rapid and mild deoxygenation of organoheteroatom oxides with the efficient electron transfer system SmI₂–tetrahydrofuran–hexamethylphosphoric triamide

Abstract

A variety of organoheteroatom oxides such as sulphoxides, sulphones, N-oxides, a phosphine oxide, and an organo tin oxide were rapidly deoxygenated at room temperature by using a stoicheiometric amount of SmI2 in tetrahydrofuran–hexamethylphosphoric triamide.
