While the one-electron reduction of (CAAC )BH Br (CAAC =1-(2,6-diisopropylphenyl)-3,3,5,5-tetramethylpyrrolidin-2-ylidene) yields a hydride-shift isomer of the corresponding tetrahydrodiborane, a further reversible reduction leads to the first stable parent boryl anion, [(CAAC )BH ] , which acts as a powerful boron nucleophile.
虽然(CAAC)BH Br（CAAC = 1-(2,6-二异丙基苯基)-3,3,5,5-四甲基吡咯烷-2-亚基）的单电子还原产生相应四氢二硼烷的氢化物迁移异构体，但进一步的可逆还原会生成第一个稳定的母体硼基阴离子[(CAAC)BH]⁻，它是一种强大的硼亲核试剂。
