(B)olefin complexes: Reductive coupling of designed monoborane precursors (see scheme; Dur=2,3,5,6-tetramethylphenyl) gives convenient access to N-heterocyclic carbene stabilized diborenes. The presence of B[BOND]B multiple bonds in the dark red diborenes is shown experimentally and theoretically. Reaction with AgCl afforded a AgI species with an unprecedented, olefin-like η2 coordination mode.
