摘要:
P,X,N-2-type phosphaporphyrins and phosphacalixphyrins (X = N, S) bearing a perfluorophenyl (C6F5) 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-C6F5 P,S-2,N-2-type sapphyrin was successfully prepared as the first example of ring-expanded phosphorus-containing porphyrin.
