A radical-mediated approach to alkene hydration is described. The present strategy capitalizes on the unique radical reactivity of hydroxamicacids, which are capable of functioning as both synthetically useful oxygen-centered radical species and suitable hydrogen atom-based donors. This reaction manifold has been applied to both alkene hydrations and tandem alkene–alkene carbocyclization processes

approach to alkene carbooxygenation usinghydroxamicacids is described. These transformations represent rare examples of direct carbooxygenations, and deliver versatile functionality to the unsaturated substrate. Included in this study are alkene oxyallylation, oxycyanation, and formal oxyacylation processes. These unique reactions capitalize on the reactivity of amidoxyl radicals in alkene additions
