tert-Butylperoxyiodane undergoes oxidation of the methylene groups α to the nitrogen atom of amides (or carbamates) yielding imides or tert-butylperoxyamide acetals, depending on the reaction conditions. A proposed mechanism involves generation of carbon-centered radicals α to the nitrogen atom.

A mechanism involving the intermediate formation of an amine radical cation by single-electron transfer is proposed for the oxidation of secondary amines with alkylperoxy-lambda(3)-iodane. On the other hand, the oxidation of acetamides probably proceeds by a radical process, which involves the direct hydrogen abstraction of the methylene group alpha to the nitrogen atom.

An organocatalytic oxidative synthesis of N-protected tetrahydroisoquinolines is described by C–Hfunctionalizationviaintermediateperoxides. The peroxides were synthesized from tert-butylhydroperoxide under metal-free thermal conditions and were converted into the final products by Bronsted acidcatalyzed substitution. The nucleophile scope was investigated in detail and proved to be broad; N-deprotection
