Indium hydride, adducts

Dichloroindium hydride (Cl2InH), generated by the reaction of InCl3 with tributyltin hydride, is also successfully used for the reduction of carbonyl compounds and for the debromination of alkyl bromides.366 This reductant has features such as the chemoselective reduction of functionalized benzaldehydes, chelation-controlled reduction of benzoin methyl ether, and 1,4-reduction of chalcone. The stable carbene and tertiary phosphine adducts of indium trihydride, InH3 CN(Mes)CH=CHN(Mes) and InH3 P(c-G6H11)3, reduce ketones to alcohols (Equation (90)).367... 

There are no reports of well-characterized InH2 or its adducts. However, the indium(II) hydride species HInNH2 and HInPH2 have been generated by thermal and photoactivated reactions of indium metal atoms with NH3 or PH3 in solid argon matrices. They have been identified by their IR spectra.
