The synthesis of oxygen-substituted N-hydroxy phthalimide derivatives is essential due to their ubiquity in natural products and pharmaceuticals. Metals or peroxides are often required for most C=C/C—H bond activation methods used for olefins, ketones, esters, aldehydes and alcohols. Using cheap and safe iodobenzene diacetate as a feasible dehydrogenation agent and N-hydroxy phthalimide as free radical precursor, the dioxidation of olefins, α-oxidation of carbonyl compounds, oxidation of aldehydes, and oxidative esterification of primary alcohols were successfully realized. This method occurs via a radical mechanism and has the characteristics of mild metal-free reaction conditions, good compatibility and wide substrate scope.

Key words: oxidative cross-coupling, phthalimide nitrogen-oxygen radical, metal-free, iodine(III)
