Abstract
Structurally well-defined palladium bis(2,2,6,6-tetramethyl-3,5-heptanedionate) complex is reported to be an efficient catalyst for the synthesis of benzimidazole and benzoxazole derivatives in good yields. A novel approach for one-pot synthesis of benzimidazoles via direct reductive amination and N-arylation followed by hydrogenation-cyclization methodology is also described.
