| Abstract |
Temperature dependent synthesis and crystal structure of the dicopper(II) complex [Cu-2(L-kappa ONO )(2)(mu-4,4 -bipy)(DMF)(2)] (1) and the dicopper(II) based coordination polymer [Cu-2(mu-L-1-kappa ONO :2KO)(2)(mu-4, 4 -bipy)](n)center dot H2O center dot nDMF (2) derived from the acyclic Schiff base 2-[(2-hydroxy-3-methoxyphenypmethylideneamino]benzenesulfonic acid (H2L) are described. Compounds 1 and 2 crystallize in monoclinic P2(1)/n and P2(1)/c systems, respectively. Crystal structure analysis reveals that the coordination polymer 2 consists of a dimeric building block which is comparable to the basic structure of 1. The compounds are isolated from the same reaction mixture but at different reaction temperatures and 1 can be converted into the coordination polymer 2. They were tested as catalysts for (both primary and secondary) alcohols oxidation. They show good catalytic activity for the solvent-and additive-free microwave (MW) assisted peroxidative (with tert-butylhydroperoxide) oxidation of cyclohexanol (up to 85\% yield of cyclohexanone) after 30 min of low power MW irradiation.
