The C-2 alkylation of ethers and N-oxides was achieved via free radical coupling reaction under metal-free conditions. The reaction conditions are mild, and the desired products can be obtained in medium to high yields with the addition of the oxidant di-tert-butyl peroxide (DTBP).
- quinoline N-oxides,
- ethers,
- alkylation,
