Reactions of thionyl chloride with C-methyl heterocycles. Part 2. The formation of [1,2]dithiolo[3,4-c]quinolin-1-ones and bis[dichloro(4-quinolyl)methyl]trisulphanes from 4-methylquinolines
Abstract
4-Methylquinolines (1) react with hot thionyl chloride to give either 4-chloro[1,2]dithiolo[3,4-c]quinolin-1-ones (2) or bis[dichloro(4-quinolyl)methyl]trisulphanes (18). The mode of formation of these products is discussed and their reactions with various reagents are described.
