The synthesis, characterization and coordination chemistry of electroneutral and electron-poor phosphane ligands is reported. The addition of diaminochlorophosphanes [compounds of the type (R2N)2PCl] to ether solutions of C2F5Li produced the corresponding diaminopentafluoroethylphosphane compounds (R2N)2PC2F5 (R2N = C4H8ON, 1; C5H10N, 2; and C8H8N, 3). Similar treatment of aminodichlorophosphanes with
报告了电子中性和电子贫化的膦配体的合成,表征和配位化学。将二氨基氯膦[(R 2 N)2 PCl类型的化合物)加到C 2 F 5 Li的醚溶液中,制得相应的二氨基五氟乙基膦化合物(R 2 N)2 PC 2 F 5(R 2 N = C 4 H 8 ON,1 ; C 5 H 10 N,2 ;和C 8 H 8 N,3)。用两个当量的C 2 F 5 Li类似地处理氨基二氯膦,可制得(R 2 N)P(C 2 F 5)2(R = C 4 H 8 ON,4 ; C 5 H 10 N,5 ; C 4 H 8 N,6;和C 8 H 8 N,7)。这些膦类化合物以高沸点液体(1、2、4-7)或固体(3)的形式分离,产率中等(44-71%)。一当量为1的取代反应– 6与Mo(CO)6生成相应的五羰基配合物(L)Mo(CO)5(1a – 6a)。热分解7用的Mo(CO)6没有取得预期的五羰基复合物。所述膦化合物1 -
