Abstract

Reaction of a 1,2-diboraallene 1 with tetradibromodiborane B₂Br₄ coordinated by a cyclic (alkyl)(amino)carbene (cAAC) in a 3:1 ratio affords a neutral tetraboron species 2 that possesses a planar tetraatomic boron(0) unit with the average oxidation state of zero. X-ray diffraction analysis and computational studies indicate that 2 features the delocalized electrons in the part of the σ-framework of the B₄ unit, as well as the conjugated Ï€-system over the C-B₃-C moiety.
