                                              A metal-free, acid-free, direct and eco-friendly nitration methodology has been developed. A tert-butyl nitrite efficiently promotes the direct C-H nitration of electron-rich arenes with good to excellent yields and regioselectivities. The practical utility of this protocol has been demonstrated in gram-scale nitration of crown ether and mono nitration of Sesamin. A plausible free radical mechanism is proposed based on detailed experimental observations.
