Although carbon radicals generated from a variety of alcohol derivatives have proven valuable in coupling and addition reactions, the direct use of alcohols as synthetically useful radical sources is less known. In this report, benzylic alcohols are shown to be effective radical precursors for addition reactions to alkenes when treated with triphenylphosphine or piperidine with the catalyst ReIO2(PPh3)2 (I)

Xanthates can be reduced to the corresponding alkane through cleavage of the sulfidebond by heating in 2-propanol in the presence of equimolar amounts of dilauroyl peroxide, added in small portions.
