A highly efficient and facile cobalt-catalyzed C–H activation and peroxidation of 2-oxindoles was reported, which provides a new pathway for the synthesis of biologically active 3-peroxy-2-oxindoles from readily available starting materials in excellent chemical yields. The resulting products could be further transformed into various substituted 3-peroxyoxindoles in good to excellent yields. The developed
Ir-catalysed alkylation of oxindole and N-methyl oxindole with a range of substituted benzyl and heteroaryl alcohols under solvent free thermal or microwave conditions afforded the corresponding C-3-monoalkylated products in high to excellent yield. (C) 2009 Elsevier Ltd. All rights reserved.

Oxindoles are readily synthesised by intramolecular addition of aryl radicals to the α-position of α,β-unsaturated N-alkylamides.
