- Facile and practical synthesis of platinum(II) porphyrins under mild conditions
-
A facile and mild method for the preparation of platinum(II) porphyrin complexes is reported. A simple treatment of freebase porphyrins with 1.5 equiv of [PtCl2(PhCN)2] in the presence of sodium propionate in refluxing chlorobenzene (bp: 131°C) affords the corresponding Pt(II) complexes in good yields within a few hours. Furthermore, the work-up processes for our methods are less complex than those for the reported ones because chlorobenzene can be easily removed by simple evaporation.

- Effect of the chemical modification of the tetrapyrrole macrocycle on the reactivity of porphyrins in complexation with Pt4+ and Pd 2+ cations
-
The reactions of 5,10,15,20-tetraphenylporpine, 5,10,15-triphenyl-20-(4- hexadecanoxyphenyl)porphine, 5,10,15,20-tetra-(4-butoxyphenyl)porphine, and 2,3,7,8,12,13,17,18-ocaethylporphine with H2PtCl6 in boiling phenol and with PdCl2 in boiling dimethylformamide are studied by spectrophotometry. Due to a strong electronic effect of the substituents, the reactivity of the tetrapyrrole macrocycle during porphyrinate formation changes by more than two orders of magnitude. Platinum(II) 5,10,15-triphenyl-20-(4-hexadecanoxyphenyl)porphinate and palladium(II) 5,10,15,20-tetra-(4-butoxyphenyl)porphinate have been synthesized and identified for the first time.
