摘要

Conversion of the neutral 1,1-dichloro-DPGI (1) (DPGI = 2,3-diphenyl-1-germaindene) to the lithium dianion (2a) or sodium dianion (2b) leads to the highly unusual phenomenon of aromatization of the GeC4 portion of 1-germaindene at the expense of the aromatic annulated Ca ring. Treatment of 2a with trimethylchlorosilane gave the 1,1-bis(trimethylsilyl)-DPGI derivative (3) in high yield. The structure of 2a was determined by X-ray crystallography and found to possess two eta(5)-coordinated lithium ions. The five-membered ring of the germaindenyl system undergoes significant carbon-carbon bond equalization upon formation of the dianion, while the remaining four carbon atoms become diene-like, exhibiting two short bonds separated by a long bond.
