The First Boron-Tellurium Double Bond: Direct Insertion of Heavy Chalcogens into a Mn=B Double Bond

Alexander Hoffmann, Dominic Auerhammer, Holger Braunschweig, Siyuan Liu, Marc-André Légaré
The base-stabilized borylene [Cp(OC)2Mn=BtBu(IMe)] readily reacts with elemental chalcogens in an insertion reaction that yields borachalcone complexes [(OC)2Mn-E=BtBu(IMe)] (E = S, Se, Te). The tellurium example features the first double bond between boron and tellurium, making Te the heaviest main-group element to make multiple bonds with boron. This unprecedented interaction has been fully investigated experimentally and computationally.
