The Synthesis and Reactions of 1-Chloro-2-Isonitrosodibenzoylethane

Abstract

T h e addition o f nitrosyl chloride t o trans-dibenzoylethylene produces only the syn-benzoyl isomer o f 1-chloro-2-isonitrosodibenzoylethane. This compound contains a hydrogen bond. It forms t w o isomeric mono-2,l-dinitro-phenylhydrazones. W h e n boiled with hydrochloric acid it is converted into 3-benzoyl-lchloro-5-phenylisouazole. T h e reactions and derivatives o f this latter compound are discussed.
