Arsine complex

There have been two other reports of racemization at arsenic in cationic metal complexes. One concerns the quantitative transformation of [Pd((R, S )-107 ](C104)2 into [Pd (R, R )-107 ](C104)2 when a solution of the former in DMSO was heated at 150°C for several minutes The transformation is irreversible and involves unprece-

Arsine complexes are especially stable for b-class metals such as Rh, Pd and Pt, and such complexes have found considerable industrial use in hydrogenation or hydroformylation of alkenes. 

Tertiary phosphine complexes have been studied intensively since the 1960s. The bulk of the work has been with phosphines, but corresponding arsine complexes are broadly similar. 

A considerable number of the tertiary phosphine and arsine complexes of iridium(III) have been synthesized [4, 8] they generally contain 6-coordinate iridium and are conventionally prepared by refluxing Na2IrCl6 with the phosphine in ethanol or 2-methoxyethanol [154]... 

The phosphine and arsine complexes of gold(I) have been intensively studied since the early 1970s. The possibilities of coordination numbers between 2 and 4 have been explored, though the use of bulky ligands is less essential than with the isoelectronic M(PR3)2 (M = Pd, Pt) compounds and the coordination numbers depend on both steric and electronic factors [71].

Low-valent arsine complexes of Co are few and these bear mostly C ligands such as CO (see Section 6.1.2.1.1 for an example).
