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.
