Oxidative Addition Reactions of Complexed Phosphine and Arsine at Platinum(0) Complexes
The reactions of E(SiMe3)3 with [W(CO)5thf] yield after alcoholysis in a one-pot reaction the complexes [(CO)5WEH3] (1) (E = P(a), As(b)). This procedure circumvents the direct use of gaseous phosphine and arsine, respectively. Complexes 1 react with [(C2H4)Pt(PPh3)2] in an oxidative addition type reaction to form the heterometallic complexes [(PPh3)2Pt(H)] (E = P(2), As(3)). Complexes 2 and 3 were obtained as mixtures of their cis- and trans-isomers, in which the contents of the trans-isomer dominates. The products were comprehensively spectroscopically characterised, and the structures of the trans-complexes 2 and 3 were determined by X-ray crystal structure analysis.
