摘要:
Metal-free trimethylgermyl anions were prepared by cleavage of the Ge-Si bond of (trimethylsilyl)trimethylgermane and the Ge-Ge bond of hexamethyldigermane with tetrabutylammonium fluoride (TBAF) in hexamethylphosphoric triamide (HMPA). The reactions of metal-free germyl anions produced by a catalytic or one-equivalent amount of TBAF with organic halides carbonyl compounds, and alpha,beta-unsaturated ketones were examined.
