Аннотация:Aminobisphenol supported germylenes (1a–3a), stannylenes (1b–3b) and plumbylenes (1c–3c) were synthesized by reaction of Lappert's tetrylenes, [(Me3Si)2N]2M (M = Ge, Sn, Pb), with corresponding aminobisphenols R1N(CH2C6H2(OH)(t-Bu)R2)2, 1–3 (1: R1 = Et, R2 = Me; 2: R1 = Et, R2 = t-Bu; 3: R1 = CH2(Py-2), R2 = t-Bu). X-ray diffraction analysis revealed different coordination mode for germylene 3a and stannylene 3b with additional nitrogen donor in the structure of the ligand. Germylene 1a was converted to the rhenium complex 1aa by the reaction with Re(CO)5Br.
