Synthesis of the fluorohydridoborate anions [BHF3]− and [1-HF2B-9,12-X2-closo-1,2-C2B10H9]− (X = H, I): deboronation of 1,2- and 1,7-dicarba-closo-dodecaboranes with anhydrous [Me4N]F†
Abstract
Deboronation of closo-1,7-C2B10H12 and 1-R1-closo-1,2-C2B10H12 (R1 = Me, Ph) with anhydrous [Me4N]F yields [Me4N][BHF3] that is the first structurally characterized anion of the series [BHxF4−x]− (x = 1–3). Deboronation of 9,12-R22-closo-1,7-C2B10H12 (R2 = H, I) gives a mixture of [Me4N][BHF3] and [Me4N][1-HF2B-9,12-R22-closo-1,2-C2B10H9].
