4,5-Disubstituted 2-mercaptoimidazoles (Ia-c) on condensation with α-halogenoketones and subsequent cyclization of the intermediate ketones (IIa-f) with PPA furnish 3,5,6-trisubstituted imidazothiazoles (IIIa-f).On the other hand, mercaptoimidazoles Ia and Ib on reaction with 1,2-dibromoethane yield sym-bis(4,5-disubstituted-imidazol-2-ylmercapto)ethanes (IVa,b).
