n-Bu4NI-catalyzed direct amination of ethers with aryl tetrazoles and triazoles via cross-dehydrogenative coupling reaction

An efficient, metal-free protocol for direct amination of ethers with aryl tetrazoles and triazoles has been developed using tetrabutylammonium iodide (TBAI) as a catalyst and tert-butyl hydroperoxide (t-BuOOH) as an oxidant. A series of ethers, aryl tetrazoles as well as triazoles are tolerated in this system, giving the corresponding products in moderate to good yields.
