Summary
The syntheses, crystal structures and catalytic activities of the polymers derived from 2-(2-pyridylmethyleneamino)\nbenzenesulfonic acid (HL), viz. [CuL(H2tma)]n (1) and [{Cu2L2(H2pma)}·(8H2O)]n (2) [H3tma =\nbenzene-1,3,5-tricarboxylic (trimesic) acid and H4pma = benzene-1,2,4,5-tetracarboxylic (pyromellitic)\nacid], are presented. Despite the comparable combinations and compositions of ligands (sulfonate and\ncarboxylate) in these two polymers the bridging moiety in 1 is sulfonate while in 2 it is carboxylate. Complexes\n1 and 2 act as catalysts in the peroxidative oxidation of cyclohexane under mild conditions using\neither the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate [bmim][PF6] or acetonitrile as\nthe solvent. The ionic liquid medium leads to increases in the yields and in the turnover numbers,\nachieved in shorter reaction times in comparison with those when using the conventional acetonitrile\nsolvent. A simple recycling of the catalysts in the ionic liquid medium is achieved without loss of activity\nand selectivity.
