A metal-free synthesis of isatins was achieved through the oxidative reactions of oxindoles with molecular oxygen in the presence of tert-butyl nitrite as an additive. This strategy provides a convenient and simple synthetic route to the construction of C=O bonds without the need for any catalyst or base. The attractive features of this reaction include its convenient procedure and mild reaction conditions.

Water induces a change in the product of radical multifunctionalization reactions of aliphatic alkenes involving an sp3 C–H functionalization by an 1,5-hydrogen shift using tert-butyl nitrite and molecular oxygen. The reaction without water, reported previously, gives nitrated γ-lactols, whereas the reaction in the presence of water produces 4-hydroxy-5-nitropentyl nitrate or 4-hydroxy-3-nitropentyl nitrate derivatives.
