Carbanions stabilized by adjacent boron have recently been generated by deprotonation of sterically hindered organoboron compounds with hindered lithium dialkylamide P and show promise as intermediates for organic synthesis. Prior to these discoveries, boron-substituted carbanions were accessible only through deboronation of compounds having three or four boronic ester groups5p6 or two boronic ester and one or two group 4 metal substituents ...
