Et3, and efficient Mediator for Xanthate Transfer Based Radical Processes.

The triethylborane mediated intermolecular addition ofdiverse carbon radicals, derived from the corresponding xanthates,to allyl acetate (10b) and 4-allyl-1,2-dimethoxybenzene (10a) wasstudied in various solvents. In most cases, the product yields in waterat room temperature were as good as, or better than, those obtained using 1,2-dichloroethane as the solvent. In contrast, ethanol in mostcases was not a useful solvent in which to conduct these reactions.
