摘要: The exchange reaction of lithium o-amidophenolate, (AP)Li2, derived from the 4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-iminobenzoquinone (imQ) with GeCl4 in hexane or thf leads to (AP)2Ge (1) (AP is a dianion imQ). latter was also obtained by interaction GeCl2·dioxane and (ISQ)Li toluene (ISQ radical anion (AP)Li2 results formation germylene 2, [(AP)Ge (2)], which reduces neutral imQ give compound 1. exposure 1 anhydrous HCl 1:1 molar ratio its o-aminophenolato derivative, (AP)(APH)GeCl (3). Free inserts into Ge–H bond (C6F5)3GeH (C6F5)3Ge(APH) (4). It another way obtaining complexes protonated ligands such as APH. Compound 3 can be easily oxidized air form stable paramagnetic complex (AP)(ISQ)GeCl (5). Complexes 3–5 were structurally investigated using single-crystal X-ray diffraction.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
