K. Mochida et al., GENERATION AND REACTIONS OF METAL-FREE TRIALKYLGERMYL ANIONS FROM SILYLGERMANE AND DIGERMANE, Journal of organometallic chemistry, 499(1-2), 1995, pp. 83-88
Metal-free trimethylgermyl anions were prepared by cleavage of the Ge-
Si bond of (trimethylsilyl)trimethylgermane and the Ge-Ge bond of hexa
methyldigermane with tetrabutylammonium fluoride (TBAF) in hexamethylp
hosphoric triamide (HMPA). The reactions of metal-free germyl anions p
roduced by a catalytic or one-equivalent amount of TBAF with organic h
alides carbonyl compounds, and alpha,beta-unsaturated ketones were exa
mined.
