Two new silyl-substituted silolide dianions (11a, 11b) have been synthesized and characterized spectroscopically. Their 1H, 29Si, and 13C NMR spectra show similarities to the known phenyl-and alkyl-substituted analogues. Reaction with ethyl bromide gave the expected diethylsilol. B3LYP/6-31 + G∗ geometry optimization revealed equalized CC distances, and also NICS values indicate significant aromaticity.Figures S1-S5 are available online in Supplemental Materials.
