通过将低价金属卤化物“GaI”、InBr和InCl与亚胺盐[Me2N=CH2]Cl反应,制备了有机镓化合物[{Me2NCH2Ga(Cl,I)2}2](1)和有机铟化合物[Me2NCH2In(Cl,Br)2]2(2)和[Me2NCH2InCl2]2(3)。化合物1和2是异卤素混合物。这些化合物通过NMR光谱和质谱进行了表征,其中1还通过单晶X射线衍射,3还通过元素分析进行了表征。在工作过程中,还分离出了化合物2和3的少量氢卤素加合物,这些加合物包含另外一个THF当量。通过单晶X射线衍射确定了这些离子性物种Me2N(H)CH2In(Br,Cl)3·THF(2·H(Cl,Br)·THF)和Me2N(H)CH2InCl3 ·THF(3 ·HCl ·THF)。将化合物1和2与MeLi进行甲基化反应,得到了两种已经通过不同制备方法获得的已知化合物[{Me2NCH2GaMe2}2]和[{Me2NCH2InMe2}2]。
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 THF. These zwitter-ionic species Me2N(H)CH2In(Br,Cl)3·THF (2·H(Cl,Br)·THF) and Me2N(H)CH2InCl3 ·THF (3 ·HCl ·THF) 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.
