Rhodium-Induced Selective B(3)/B(6)-Disubstitution ofortho-Carborane-1,2-dithiolate

Abstract

The various reactive sites in the 16 e complex 1 invite addition reactions with alkynes. After addition of 2 to one of the Rh-S bonds, B-H activation takes place which finally leads to the complex 3, in which a B(3)/B(6)-disubstituted o-carborane cage is present for the first time.
