The Effect of Disulphide Bond in Metallodeuteroporphyrin on Their Catalytic Activity for Aerobic Oxidation of Cyclohexane
Two novel types of metallo-deuteroporphyrins bearing the disulphide bond were employed to investigate their catalytic activity in oxidation of cyclohexane with molecular oxygen (air) to cyclohexanol and cyclohexanone without the use of sacriﬁcial co-reductant. The catalytic activity of metallo-deuteroporphyrin disulphide derivatives was obvious difference when different metals were incorporated into the porphyrin. However, the same metal cobalt porphyrin complexes exhibited the different catalytic efficiency due to the effect of substituents. Co(II)deuteroporphyrin disulphide derivative is more active than other metallo-porphyrin complexes. On the basis of the obtained results the new reaction process is discussed.
