A carbohydrate derivative that contains a sulfur atom bonded to two carbon atoms is capable of forming carbon-centered radicals. A common pathway for radical formation in compounds of this type is homolytic cleavage of a carbon–sulfur bond brought about by group abstraction (eq 1). When the sulfur atom in a C–S bond is part of an electronegative group, as is the case in a glycosyl phenyl sulfone, electron transfer of the type shown in Scheme 1 represents another pathway to carbon-centered radical formation. A beginning point for discussing these reactions is examining their possible mechanisms.
