摘要：

This paper presents aspects concerning the catalytic activity of several transition metal coordination polymers with the general formula (2)(infinity)[Me(II)X-2(4,4'bipyridine)] (Me(II) = Co, Ni, Cu; X = Cl-, CH3OCO-, and acetylacetonate) towards the epoxidation of cyclohexene with molecular oxygen in the presence of isobutyraldehyde as reductant. The obtained results proved that all the investigated catalysts showed a high selectivity for epoxidation (over 88%). The conversion of cyclohexene was found to depend on the nature of both the transition metal cation and the ligand X. The most active catalyst was found to be (2)(infinity)[Co(II)(CH3OCO)(2)(4,4'bipyridine)]. (C) 2011 Published by Elsevier B.V.
