Abstract
Abstract A highly ordered nanoporous aluminosilicate (MMZ Y) is prepared and employed as a catalyst for the synthesis of benzimidazoles from 1, 2-diaminobenzene and aromatic aldehydes. In all the cases, the reactions are highly chemoselective and afford 1, 2- disubstituted benzimidazoles in excellent yield. The catalyst was characterized by electron microscopy and X-ray methods and its other advantages like functional tolerance, ...
