โœฆ Synopsis

Oxygen centered radicals, formed by the photolysis of derivatives of N-hydroxy-2-thiopyridone, have been trapped by vinyl ethers. In the case of the benzoyloxy radical, smooth deoxygenation is effected by "'P compounds.

Evidence for the formation of the dimethyltbutylsilyloxy and of the hydroxy radical is also presented.

Reaction of methanesulfonyl cyanide or p-toluenesulfonyl cyanide with carbon radicals generated from the acyl derivatives of N-hydroxy-2-thiopyridone gives the corresponding nitriles in high yield. A mechanistic scheme is suggested. There are many synthetic applications of carbon radicals generated
