It is challenging to develop simple and low cost catalytic systems while maintaining high reactivity and selectivity. An iron-catalyzed intramolecular C-H amination of sulfamate esters using simple and cheap ligands is reported with general substrate scope (31 examples, up to 95% yield). The addition of second ligand, bipyridine, is able to accelerate the reaction and increase the yield. The ready availability of these iron catalysts provides a promising approach to selective introduction of nitrogen into hydrocarbon feedstock.

The invention provides novel manganese catalysts such as [Mn(tBuPc)], which are general for the amination of all types of C(sp3)-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1o aliphatic

The whole pybox and dice: Highly enantioselective amination reactions of both allylic and benzylic C-H bonds are catalyzed by cationic ruthenium(II)-pybox complexes (see structure). A novel mode of stereocontrol, which is induced by the versatile pybox ligand, is proposed to account for the excellent enantioselectivity in these reactions. Boc = tert-butoxycarbonyl, pybox = pyridine bisoxazoline. (Chemical Equation Presented)
