Radicals formed from the esters of thiohydroxamic acids readily add to electron deficient olefins to give adducts of potential synthetic value in variable yield. In certain cases the added sulphur function is easily eliminated with reformation of olefin. Functional group manipulation in complexe na

โฆ Synopsis
Acyl derivatives of thiohydroxamic acids1 and hydroxamic acids2 are useful precursors of various carbon-centered (mostly alkyl or substituted alkyl). nitrogencentered, oxygen-centemd and other radicals.~ The most often used and most versatile examples are various O-acyl derivatives 2 (Barton esters) of the thiohydroxamic acid N-hydroxy-2-thiopyridone
