An electron-deficient[CpERhCl2]2 catalyzed annulation of N-pentafluorophenylbenzamides with internal alkynes was successfully established under mild reaction conditions,with the assistance of Lewis acid silver salt.Pa...
N-(4-Methyl-3-tolylthiazol-2(3H)-ylidene) substituted benzamides (2a-o) were synthesized in good to excellent yields by the base-catalyzed direct cyclization of corresponding 1-tolyl-3-aryl thioureas (la-o) wi...
