Binuclear organometallic compounds. Part II. Reactions of triorganotin hydrides with iridium(I) and rhodium(I) complexes

Abstract

Hydrostannation of the iridium(I) complexes, trans-IrXCOL₂(where X = Cl, Br, or I; L = PPh₃, PPh₂Me, or PPhEt₂) by the tri-organotin hydrides, R₃SnH (where R = Me, Et, or Ph), yields the iridium(III) species, R₃SnIr-HXCOL₂, the stereochemical configurations of which are discussed on the basis of i.r. and n.m.r. data. The rhodium(I) complex, RhClCO(PPhEt₂)₂ does not react with tri-organotin hydrides, and, although RhCl(PPh₃)₃ does react, hydrostannation does not occur.
