Abstract

Abstract: a,a,a-Trichloromethyl and a,a,a-trifluoromethyl aromatic compounds react with o-aminothiophenol and o-aminophenol in polyphosphoric acid (PPA) to produce 2-arylbenzothiazoles and 2-arylbenzoxazoles in high yields. ... Benzothiazoles and benzoxazoles are the basis of numerous optical bright-
