Abstract Monomerie diiodides of 2,4,6-tri(tert-butyl)phenyl = (s-Mes), 2,4,6-triisopropylphenyl = (Trip)-and 2,4-di-tert-butyl-6-methylphenyl = (DBMP)-gallium and -indium were prepared by the reaction of the lithiated aryls with MI3 (M = Ga, In) in hexane/Et2O. s-MesInI2 (1), s-Mes2InI (2), s-MesGaI2 (3), s-Mes2GaI (4), Trip2InI (5) and (DBMP)2InI (6) were obtained and characterized by their mass and NMR spectra (1H, 13C), and/or by elemental analyses. An X-ray crystal structure analysis was carried out for 1.
