Oxygen-Induced Transmetallation of Organoboranes with Diphenyl Ditelluride
Diphenyl ditelluride rapidly reacted with trialkylboranes in the presence of oxygen to give alkyl phenyl tellurides in high yields.The facile rection proceeds via a free-radical mechanism induced by a stoichiometric amount of oxygen.A combination of this transmetallation with hydroboration provides an alternative method for hydrotelluration of olefins.
