Oxidative Coupling of 3-Oxindoles with Indoles and Arenes.

ABSTRACT: A highly efficient method for the oxidative coupling of 2-substituted 3-oxindoles with aromatic compounds to form 2,2-disubstituted indolin-3-ones with broad scope is described. This work utilized oxygen as the terminal oxidant and a base-metal catalyst under mild conditions instead of toxic/precious-metal reagents and higher-molecular-weight oxidants. Quaternary structures were produced in modest-to-excellent yields (up to 96 %) without prefunctionalization.
