PPRS

Martin et al. [69] undertook a study of the kinetics and mechanism of NBR hydrogenation using various Ru complexes. They examined the activity of RuXCl-(C0)L2 (X = H, Ph, or CH=CHPh L = PCy3, PPr,... 

Crystalline OsH6(PPr 2Ph)2 was also made by reduction 0s02Cl2(PPr2Ph)2 OsH6(PPr 2Ph)2... 

PR3, e.g. PPh3, PMe2Ph, PPr Ph), though short reaction times are necessary to prevent further reduction and the trialkyl phosphines are too strongly reducing to allow the isolation of their complexes [140]. 

Complexes of triisopropylphosphine (cone angle 160°) [69, 117]. In contrast to less bulky trialkylphosphines, a complex RhCl3(PPr3)3 has only been made by reaction at 0°C at higher temperatures, hydrides like RhHCl2(PPr 3)2 result (the less bulky tri(n-propyl)phosphine gives the 3 1 complex at reflux). 

Controlled chlorination with A-chlorosuccinimide results in the formation of square pyramidal RhHCl2(PPr3)2 and planar RhCl2(PPr 3)2 (Figure 2.65).
