A di-substituted boron dication and its hydride-induced transformation to an NHC-stabilized borabenzene.


The intrinsic electron deficiency of borane derivatives stems from the presence of a low-lying empty p orbital on the boron atom. Methods to further increase the Lewis acidity of boranes include the incorporation of a boron atom into an anti-aromatic system and the introduction of electronwithdrawing groups, such as halogens, Lewis acidic elements, and… (More)
