Herein, we describe a simple, highly efficient and environmentally friendly protocol for the synthesis of benzimidazoles, benzoxazoles, benzothiazoles, 3,4-dihydropyrimidin-2-ones/ thiones and quinoxalines derivatives using hybrid crystal NH3(CH2)6NH3SiF6 as a catalyst. Use of recyclable catalyst, easy work-up procedure, excellent yields, short reaction times and scalability are the important practical features of the present protocol.
