Co-ordination compounds of indium. Part 40. Reactions of non-aqueous solutions of inidium(I) halides

Abstract

Inidium(I) halides can be dissolved in toluene containing certain neutral donor ligands below ca. 0 °C. The simplest solute species in InBr–toluene–NNN′N′-tetramethylethylenediamine (tmen) is InBr·3tmen which slowly precipitates solid InBr·0.5tmen. Disproportionation of InX occurs above 0 °C, yielding indium metal and In^II or In^III halide complexes, depending on X and the neutral ligand. Solutions of InX (X = Br or I) can oxidatively insert C–X bonds producing organoindium(III) halides.
