The base‐stabilized borylene [Cp(OC) 2 Mn=B t Bu(IMe)] readily reacts with elemental chalcogens in an insertion reaction that yields borachalcone complexes [Cp(OC) 2 Mn‐E=B t Bu(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 both experimentally and computationally.
