The 9H‐9‐Borafluorene Dianion: A Surrogate for Elusive Diarylboryl Anion Nucleophiles
Double reduction of the THF adduct of 9H‐9‐borafluorene (1⋅THF) with excess alkali metal affords the dianion salts M(2)[1] in essentially quantitative yields (M=Li–K). Even though the added charge is stabilized through π delocalization, [1](2−) acts as a formal boron nucleophile toward organoboron (...
