Oxidative cross-coupling of pyridine N-oxides and ethers between C(sp(2))-H/C(sp(3))-H bonds under transition-metal-free conditions.

A novel and efficient method based on the cross-coupling reactions of pyridine N-oxides with ethers between C(sp(2))-H/C(sp(3))-H bonds in the presence of TBHP was developed. The strategy provides an alternative approach to the pyridine moiety under transition-metal-free conditions.
