Synthesis of bis(aryloxy)fluoromethanes using a heterodihalocarbene strategy

Abstract

A side-product present in the herbicide pyroxasulfone was synthesized. The construction of a bis(aryloxy)fluoromethane moiety was necessary, for which no existing method was available. We report a simple, new procedure which we applied to the synthesis of some of these unusual structures.
