p-complexes of diborynes with main group atoms
journal contribution
posted on 2023-06-07, 07:15 authored by William C Ewing, Theresa Dellermann, Y T Angel Wong, James D Mattock, Alfredo VargasAlfredo Vargas, David L Bryce, Rian D Dewhurst, Holger BraunschweigWe present herein an in-depth study of complexes in which a molecule containing a boron-boron triple bond is bound to tellurate cations. The analysis allows the description of these salts as true p complexes between the B-B triple bond and the tellurium center. These complexes thus extend the well-known Dewar-Chatt-Duncanson model of bonding to compounds made up solely of p block elements. Structural, spectroscopic and computational evidence is offered to argue that a set of recently reported heterocycles consisting of phenyltellurium cations complexed to diborynes bear all the hallmarks of p-complexes in the p-complex/metallacycle continuum envisioned by Joseph Chatt. Described as such, these compounds are unique in representing the extreme of a metal-free continuum with conventional unsaturated three-membered rings (cyclopropenes, azirenes, borirenes) occupying the opposite end.
