合成了一系列新的吡咯基四磷配体，并将其用于Rh催化的内烯烃异构化-氢甲酰化反应。结果表明，联苯的3，3‘，5，5’位取代基对线性选择性有很大影响，其中烷基取代的四磷配体的线性选择性最好(对于2-辛烯，n：i可达207，对2-己烯，n：i可达362)。
A series of new pyrrole-based tetraphosphorus ligands were synthesized and used for Rh-catalyzed isomerization-hydroformylation of internal olefins. It was found that the substituents at the 3,3',5,5'-positions of the biphenyl greatly effected the linear selectivity, and the alkyl-substituted tetraphosphorus ligands gave the best results (for 2-octene, n: i up to 207, for 2-hexene, n: i up to 362).
