Die vorliegende Erfindung betriff neuartige Phosphorverbindungen, ein Verfahren zur Herstellung der Phosphorverbindungen und deren Zwischenprodukte. Weiterhin umfass der Rahmen der Erfindung aus den Phosphorverbindungen herstellbare Katalysatoren und deren Anwendung in katalytischen Prozessen, inbesondere in asymmetrischen katalytischen Prozessen.
Highly distorted d8-rhodium(+I) and d10-rhodium(-I) complexes: synthesis, reactivity, and structures in solution and solid state
yield anionic rhodate complexes [Rh(RCH2troppph)(metroppph)]− (R = H, Me, n-Bu, Ph) that formally have a d10 valenceelectron configuration. The rhodate [Rh(metroppph)2]− can be obtained directly by reduction of cation [Rh(metroppph)2]+ with alkali metals. In a sym-proportionation reaction [Rh(metroppph)2]+ and [Rh(metroppph)2]− give the neutral d9-[Rh(metroppph)2] radical (K = 1.1 × 107), which is
