Intermolecular Ritter-Type C–H Amination of Unactivated sp3Carbons
摘要:
Intermolecular Ritter-type C-H amination of unactivated sp(3) carbons has been developed. This new reaction proceeds under mild conditions using readily available reagents and an inexpensive source of nitrogen (acetonitrile). A broad scope of substrates can be aminated with this method since many functional groups are tolerated. This reaction also allows for the direct, innate C H amination of a variety of hydrocarbons such as cyclohexane without the need of prefunctionalization or installation of a directing group.
The reaction of olefins with anhydrous mercury-(II) nitrate in the presence of primary amides leads, after in situ alkaline sodium borohydride reduction, to the corresponding N-substituted amides; this procedure provides a new, convenient method for the Markovnikov amidation of carbon–carbon double bonds.

aliphatic C–H bonds, ubiquitous in molecular structures, could allow ready access to diverse chemical products. While enzymatic oxygenation of C–H bonds is well established, the analogous enzymatic nitrogen functionalization is still unknown; nature is reliant on preoxidized compounds for nitrogen incorporation. Likewise, synthetic methods for selective nitrogen derivatization of unbiased C–H bonds remain
