SHEET POLYMER AND ITS COMPLEXES - II - PREPARATION AND CATALYTIC ACTIVITY OF POLYMERIC TETRAKISPHENYLPORPHYRIN FILMS CROSS-LINKED BY 4,4'-BIPHENYLENE-BISULFOATE

The polymeric o-tetra-(4,4'-biphenylene-bisulfo)-phenylporphyrin and i ts complexes (PMTBPBSOPP, M = Co, Mn, Cu, and Zn) have been prepared i n the presence of phase-transfer catalyst and characterized with ultra violet-visible spectra, infrared spectra, X-ray photoelectron spectros copy, and scanning electron microscopy. Its catalytic activity in oxid ation of cumene, ethylbenzene, and cyclohexene by molecular oxygen hav e been studied. Cumene afforded efficiently cumenol (1), acetophenone (2), together with a small amount of 4-methyl acetophenone (3). Ethylb enzene afforded efficiently alpha-methylbenzyl alcohol(4) and acetophe none (5). Cyclohexene catalyzed by PCuTBPBSOPP in the presence of mole cular oxygen afforded 1,2-cyclohexanediol (6) and 1,2-cyclohexanedione (7). (C) 1998 John Wiley & Sons, Inc.
