Oxidative annulation of acetophenones and 2-aminobenzothiazoles catalyzed by reusable nickel-doped LaMnO₃ perovskites

The synthesis of imidazol[2,1- b ]benzothiazoles catalyzed by perovskites namely Ni-doped LaMnO 3 is reported. The conditions are tolerant of many functionalities. The perovskites were recyclable up to 3 times while structure was still remained.
