The interaction of Co(II)- and Co(III)-5,10,15,20-tetraphenylporphyrins with tert-butylhydroxyperoxide and di-tert-butylhydroxyperoxide in benzene at 298 K were studied by spectrophotometry and 1H NMR spectroscopy. Kinetic parameters of the destruction reactions of porphyrin macrocycle depending on the nature of peroxide the valence of cobalt cation, and the presence and nature of axial ligands were

found that complex reactivity increased with the leaving group ability of the halide. A trans-dichlorovinyl cobalt porphyrincomplex, (TPP)Co(Z-CClCHCl), was also prepared through the reaction of (TPP)CoNa and TCE. The structures of (TPP)Co(E-CHCHBr), (TPP)Co(Z-CClCHCl), and (TPP)Co(C(2)H) are reported. The C-C bond length of the vinyl group was found to vary for the beta-halovinyl complexes (TPP)Co(E-CHCHX)

The photodegradation reaction rate of 4-chlorophenol (4-CP) with a titanium silicalite–2 (TS-2) catalyst is found to be faster in the initial stage than with TiO2. This is primarily due to the stronger adsorption of 4-CP on the hydrophobic surface of the TS-2 catalyst. The hydrophobicity is evaluated by determining the distribution coefficients (D) between TS-2 and aqueous medium using a variety of aromatic hydrocarbons. The larger the D, the faster the initial reaction rate. The D correlates with solubility in water and partition coefficient, log Poct.
