The reaction of trimethylindium with one equivalent of salicylaldehyde, 2-carboxybenzaldehyde, 2-pyrrolidinone or N,N'-diphenylacetamidine results in the formation of the corresponding dimethylindium derivatives in good yields.The product obtained from the reaction with salicylaldehyde has been shown by a single crystal X-ray diffraction study to consist of centrosymmetric dimers with five-coordinate indium atoms, In-C 2.122(5), In-O(CHO) 2.341(4), In-O(OH) 2.188(3) and 2.383(3) Angstroem.The reactions between triethylindium and phenylacetylene and ethanolamine are described.
