Synthesis of substituted phenyltrichlorocyclopropene derivatives using friedel-crafts reaction

Abstract

Tetrachlorocyclopropene has been prepared smoothly by the dehydrochlorination of pentachlorocyclopropane which could be obtained easily from sodium trichloroacetate and trichloroethylene in 1,2-dimethoxyethane. By the reaction of aromatic hydrocarbons with tetrachlorocyclopropene and aluminium chloride, seven new substituted phenyltrichlorocyclopropene derivatives have been prepared. The structures of these products were characterized by means of spectroscopic methods.
