摘要
1-Lithio-1-phenyl- and 1-lithio-1-trimethylsilylstannoles were synthesized and the corresponding lithium salts of stannole anions were characterized by X-ray diffraction analysis. The five-membered rings of the two lithium salts are planar with remarkable alternation of the C-C bonds, suggesting that they are both non-aromatic. Theoretical calculations are also carried out to discuss their electronic nature.
