摘要：

Reduction of 1,1-diphenylstannaindene with excess lithium gave the intermediary 1-phenyl-1-stannaindenyl anion, which was further reduced to provide the 1-stannaindenyl dianion. The remarkable upfield Li-7 NMR resonance in the dianion and the theoretical calculation suggest that the 1-stannaindenyl dianion has considerable aromatic character, as was observed in the sila- and germaindenyl dianions. Reaction of the 1-stannaindenyl dianion with tert-butyl chloride gave the 1-tert-butyl-1-stannaindenyl anion, as evidenced by NMR detection as well as a trapping experiment.
