Abstract
The organogallium compound [{Me2NCH2Ga(Cl,I)(2)}(2)] (1) and the organoindium compounds [Me2NCH2In(Cl,Br)(2)](2) (2) and [Me2NCH2InCl2](2) (3) have been prepared by the reactions of the low valent metal halides "GaI", InBr and InCl with the iminium salt [Me2N=CH2]Cl. Compounds 1 and 2 are heterohalogen mixtures. These compounds were characterised by NMR spectroscopy and mass spectrometry, 1 furthermore by single crystal X-ray diffraction and 3 by elemental analysis. During the work-up procedure, minor amounts of hydrogen halide adducts of compounds 2 and 3 were isolated as single crystals, which contain a further equivalent of THE These zwitter-ionic species Me2N(H)CH2In(Br,Cl)(3)center dot THF (2-H(Cl,Br)center dot THF) and Me2N(H)CH2InCl3 center dot THF (3 center dot HCl center dot HF) were identified by single crystal X-ray diffraction. Methylation reactions of compounds 1 and 2 with MeLi gave two well-established compounds [{Me2NCH2GaMe2}(2)] and [{Me2NCH2InMe2}(2)], which were obtained previously by different preparation procedures.
