2，18-双（二苯基膦基）卟啉与10族过渡金属盐进行外围环化反应，得到相应的卟啉基PCP钳形配合物。卟啉平面和PCP钳单元明显共面，应变小。研究了外围卟啉钳形配合物在苯甲醛与烯丙基锡烷烯丙基化反应和查尔酮1，4-还原反应中的催化活性，揭示了内金属与外金属之间的电子相互作用.
2,18-Bis(diphenylphosphino)porphyrins undergo peripheral cyclometalation with group10 transition-metal salts to afford the corresponding porphyrin-based PCP pincer complexes. The porphyrinic plane and the PCP-pincer unit are apparently coplanar, with small strain. The catalytic activities of the porphyrin-based pincer complexes at the periphery were investigated in the allylation of benzaldehyde with allylstannane and in the 1,4-reduction of chalcone to discover the electronic interplay between the inner metal and the outer metal in catalysis.
