Übergangsmetallphosphidokomplexe, III [1] Neuartige Nickel-Phosphor-Drei-und Vierringkomplexe / Transition Metal Phosphido Complexes, III [1] Novel Nickel Phosphorus Three-, and Four-Membered Ring Complexes

Abstract

Abstract (R3P)2NiCl2 and LiP(SiMe3)2 react in a complex reaction sequence finally yielding (R3P)2Ni(PSiMe3)2 (5), containing a three-membered PNiP ring system, and [R3PNiP(SiMe3)2]2 (6), containing a (PNi)2 four-membered ring system with a nickel-nickel bond, respectively. NMR data are reported.
