✦ Synopsis

Ruthenium-carborane complexes 1±3 mediated the Kharasch addition of carbon tetrachloride across ole®ns with high yields which markedly depended on the catalyst and the substrate used. In addition, the atom transfer radical polymerisation of methyl methacrylate could be carried out in a highly controlled way.

The homobimetallic ruthenium Schiff base complexes Ia-f mediated the atom transfer radical addition (ATRA) of carbon tetrachloride across olefins in excellent yields which markedly depended on the catalyst and the substrate used. The best catalytic system Ic is able to compete with the highest perfo
