The exchange reaction of lithium o-amidophenolate, (AP)Li2, derived from the reaction of 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 of imQ). The latter was also obtained by the interaction of GeCl2·dioxane and (ISQ)Li in toluene (ISQ is a radical anion of imQ). The reaction of (AP)Li2 with GeCl 2·dioxane in thf results in the formation of germylene 2, [(AP)Ge (2)], which reduces neutral imQ to give compound 1. The exposure of 1 in thf to anhydrous HCl in a 1:1 molar ratio leads to its o-aminophenolato derivative, (AP)(APH)GeCl (3). Free imQ inserts into the Ge-H bond of (C 6F5)3GeH in thf to give (C6F 5)3Ge(APH) (4). It is another way of obtaining complexes with protonated ligands such as APH. Compound 3 can be easily oxidized by air to form the stable paramagnetic complex (AP)(ISQ)GeCl (5). Complexes 1 and 3-5 were structurally investigated by using single-crystal X-ray diffraction.
