Generation of a Carbene-Stabilized Bora-borylene and its Insertion into a C-H Bond
A novel NHC adduct of a dihalodiborane(4), 1, is reduced by KC(8) with formation of the five-membered boracycle 2. The reaction most likely proceeds via C H insertion of an intermediate NHC-stabilized free boraborylene species.
