Nickel-Catalyzed Remote C(sp³)–N/O Bond Formation of Alkenes with Unactivated Amines and Alcohols

Transition metal-catalyzed remote hydrofunctionalization of alkenes is an efficient method to realize C(sp3)–H functionalization. However, remote hydrofunctionalization of alkenes with unactivated amines and alcohols has not been successfully developed to date. Herein, we report an efficient nickel-catalyzed remote hydroamination and hydroetherification of alkenes with unactivated amines and alcohols, accessing a series of gem-diamine and N,O-acetal derivatives in good to high yields (up to 93%) and exclusive regioselectivities. The mechanistic investigations and DFT computations indicated that the use of 2-iodo-2-methylpropane (tBuI) as both a mild hydride source and radical precursor was essential to afford the remote functionalized products. This research work provides an efficient method to install an amino or alkoxyl group at the C(sp3)–H position that is far from the double bond of alkenes.
