Generation and reactions of metal-free trialkylgermyl anions from silylgermane and digermane
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.

Calcium atoms are thought to be inserted into E–E′ bonds of group 4B catenates, Me3E–E′Me2R (E, E′=Si, Ge, Sn; R=Me, Cl) to give the corresponding Me3E–Ca–E′Me2R compounds.
