Catalytic processes in diorganotelluride

The modifications to the procedure of H Suzuki, A Kondo and A Osuka which describes a catalytic version of stoichiometric reactions are limited by the reversibility of the process. The procedure is more general for vic-dibromides which worked with at least one benzylic bromide. Results indicate that the more electron-rich diorganotellurides are better debrominating agents than (p-CH3OC6H4)2Te in stoichiometric reactions.
