资源简介：
Reactions of R2P–P(SiMe3)Li (R = tBu, iPr, iPr2N, Et2N) with [Cp2WCl2] yield terminal phosphanylphosphido complexes [Cp(C5H4P-PR2)WH] or [Cp{C5H4P-PR2}W(SiMe3)] by way of a hydrogen or SiMe3 migration to tungsten. The solid-state structures of [Cp(C5H4P–PtBu2)WH] and [Cp(C5H4P-PNEt2)WH] were established by single-crystal X-ray diffraction. Two stereoisomers of [Cp(C5H4P–PtBu2)WH] were identified by solution NMR spectroscopy. Reaction of iPr2P–P(SiMe3)Li with [Cp2WCl2] yields red crystals of dimeric phosphinidene complex [Cp(C5H4P)W]2 as side product.
