摘要：

The synthesis and reactivity of an NPN-chelating ligand containing a nontrigonal phosphorous triamide center (L1 = P(N(o-N(2-pyridyl)C6H4)(2)) is reported. Metalation of L1 with RuCl2 (PPh3)(3) gives RuCl2 (PPh3)-(L1) (2). By contrast, metalation of Ll with RuHCl-(CO)(PPh3)(3) yields RuCl(CO)(PPh 3)(L1(H)) (3), a chelated 10-P-5 ruthenahydridophosphorane, via net insertion into the Ru-H bond. Hydride abstraction from 3 with Ph3CPF6 gives [RuCl(CO)(PPh3)(L1)]PF6 (4); reaction of 4 with NaBH4 returns 3.
