✦ Synopsis
The polymeric meso-tetra-(4,4 -biphenylene-bisulfo)-phenylporphyrin and its complexes (PMTBPBSOPP, M Å Co, Mn, Cu, and Zn) have been prepared in the presence of phase-transfer catalyst and characterized with ultraviolet-visible spectra, infrared spectra, X-ray photoelectron spectroscopy, and scanning electron microscopy. Its catalytic activity in oxidation of cumene, ethylbenzene, and cyclohexene by molecular oxygen have been studied. Cumene afforded efficiently cumenol (1), acetophenone (2), together with a small amount of 4-methyl acetophenone (3). Ethylbenzene afforded efficiently a-methylbenzyl alcohol (4) and acetophenone (5). Cyclohexene catalyzed by PCuTBPBSOPP in the presence of molecular oxygen afforded 1,2-cyclohexanediol (6) and 1,2-cyclohexanedione (7).
