Selective Nitration of Aromatic Compounds with Bismuth Subnitrate and Thionyl Chloride

Abstract

Bismuth subnitrate/thionyl chloride have been found to be an efficient combination of reagents for nitration of a wide range of aromatic compounds in dichloromethane. Phenols, in particular, were easily mononitrated and dinitrated with the reagents by controlling the stoichiometry,
