Remarkable effects of P-perfluorophenyl group on the synthesis of core-modified phosphaporphyrinoids and phosphadithiasapphyrin.
P,X,N(2)-type phosphaporphyrins and phosphacalixphyrins (X = N, S) bearing a perfluorophenyl (C(6)F(5)) group at the core phosphorus atom were prepared in high overall yield from 1-perfluorophenyl-2,5-di(ethoxycarbonyl)phosphole as a common starting material. In addition, P-C(6)F(5) P,S(2),N(2)-type sapphyrin was successfully prepared as the first example of ring-expanded phosphorus-containing porphyrin.
