Reaction of thiourea and substituted thioureas with 1,3-dibromopropyne

10.1134/S1070363208100228

The study investigates the reaction of thiourea and various substituted thioureas with 1,3-dibromopropyne to synthesize different thiazolidine derivatives. The chemicals involved include thiourea, N-phenylthiourea, N,N'-diphenylthiourea, N-acetylthiourea, and 1,3-dibromopropyne. These reactants are used to produce 4-bromomethylidene-2-imino(phenylimino, acetylimino)-1,3-thiazolidine hydrobromides and 4-bromomethylidene-2-acetylimino-1,3-thiazolidine under different solvents and temperature conditions. The study explores the reaction mechanism, which likely involves the formation of intermediate bromoethynylmethylsulfides that cyclize into the final thiazolidine products. The products' structures are confirmed through elemental analysis and IR, 1H and 13C NMR spectroscopy data.
