A pentanuclear Er (III) coordination cluster as a catalyst for selective synthesis of 1,2-disubstituted benzimidazoles
A new tridentate ligand (H3L) was prepared from the reaction of 6-formyl-2-(hydroxymethyl)-4-tert-butylphenol and 2-amino-4-nitrophenol. The ligand H3L and acetylacetone were treated with Er (NO3)(3)center dot 5H(2)O, which resulted in the formation of a pentanuclear coordination cluster [Er-5(LH)(4)(acac)(4)(mu(3)-O)(mu(3)-OH)(H2O)(2)](.)5H(2)O (1) (acac = acetylacetonate). Five Er (III) ions are arranged in a nonlinear fashion in 1. Complex 1 was utilized as a catalyst towards the selective synthesis of 1,2-disubstituted benzimidazole derivatives involving o-phenylenediamine and different aldehydes. Yields of 1,2-disubstituted benzimidazole derivatives were in the range of 66%-91%. This study demonstrates the first-ever approach to employ a homo- and pentanuclear lanthanide coordination cluster for catalyzing the synthesis of 1,2-disubstituted benzimidazoles.
