A highly efficient method for the oxidative coupling of 2‐substituted3‐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
