Abstract
New 8-(methoxynaphthyl)hydridogermanium triflates and iodides were syn thesized by treatment of the corresponding germanes with trifluorometh anesulfonic acid or I-2. Their characterization by H-1 and C-13 NMR an d IR spectroscopy is reported. In the solid state, bis(8-methoxynaphth yl)hydridogermanium triflate (6) exhibits a 5-coordinate germanium ato m weakly linked to the triflate anion. The germyl iodide rapidly gives the germoxolene with loss of MeI when it is heated in CH3CN. With H2O , amine, and DMSO, the germyl triflates react quantitatively to form n ew complexes which can be isolated and characterized. The X-ray crysta l structure of the hydrate of bis(8-methoxynaphthyl)hydridogermanium t riflate (11) shows the predominant formation of a hydrated germyl cati on. Several tentative approaches to prepare germanols failed and alway s gave stable germoxanes instead.
