The method features metal-free, room temperature and broad substrate scopes as well as no extra oxidant.This process applies to various substituent groups and gives products in moderate to good yield. Finally, a rational mechanism was proposed.展开更多

This method can tolerate considerable functional groups such as electrondonating groups and electron-withdrawing groups through CààC cross-coupling. Moreover, we obtain the products with moderate yields in an efficient way. Finally, a plausible mechanism is proposed.展开更多
