THE INSERTION OF INDIUM(I) HALIDES INTO THE M-X BOND OF SOME MAIN GROUP ORGANOMETALLIC HALIDES

Article abstract of DOI:10.1016/0022-328X(87)80390-X

Indium(I) halides (InX) react with Ph3SnX (X=Cl, Br, I) in toluene/tmed mixtures to give Ph3SnInX2*tmed compounds (tmed=N,N,N',N'-tetramethylethanediamine), and Ph3Sn(OAc) yields Ph3SnIn(OAc)X2*tmed.Vibrational spectra and conductivities of these compounds, and of the salt Et4N, show that these are the first examples of Sn-In bonded molecules.With Me3SnCl, Ph3SnH, Ph3GeCl, Ph3PbCl and Ph2PCl, no oxidative addition reaction was observed.The results are compatible with previous discussions of the mechanism of such reactions, based on the insertion of indium into the M-X bond.
