Abstract
The 1,3-bromoboration of [W(N2)2(dppe)2] (dppe = 1,2-bis(diphenylphosphino)ethane) with B2Br4(SMe2)2 in the presence of various Lewis bases L yields diboranyldiazenido complexes, with L coordinating either at the terminal or internal boron atom. The 2 : 1 reaction of [W(N2)2(dppe)2] and B2Br4(SMe2)2 yields a 1,2-bis(diazenido)diborane-bridged ditungsten complex with a fully planar π-conjugated BrWN2B2Br2N2WBr core.
