Alkyne coupling in rhenacarbaborane chemistry. Structure of [1,2-mu-NHBut-2,2-(CO)(2)-3,2-sigma:eta 2-(C(=CHBut)-CH=CHBut)-closo-2,1-ReCB10H9].
The butadienyl moiety in the title compound is bound to both cage-boron and rhenium vertices, and arises from coupling of two alkyne molecules at the rhenium centre, unprecedented in metallacarbaborane chemistry.
