Solvent-free synthesis of 1-( p-toluenesulfonyloxy)-1,2-benziodoxol-3(1 H)-one from Dess–Martin periodinane and its synthetic utility for α-tosyloxylation of ketones

Abstract

The solvent-free synthesis of 1-( p-toluenesulfonyloxy)-1,2-benziodoxol-3(1 H)-one is reported from Dess–Martin periodinane and p-toluenesulfonic acid monohydrate using a grinding technique and is subsequently utilized for the α-tosyloxylation of a range of enolisable ketones.
