摘要

Abstract A series of substituted benzimidazoles, benzothiazoles, and benzoxazoles was synthesized by combining 1, 2-phenylenediamine, 2-aminothiophenol, or 2-aminophenol with aryl, heteroaryl, aliphatic, α, β-unsaturated aldehydes in the presence of nano ceria (CeO 2) as an efficient heterogeneous catalyst.
