C-H bond oxidation reactions underscore the existing paradigm wherein high reactivity and high selectivity are inversely correlated. The development of catalysts capable of oxidizing strong aliphatic C(sp3)-H bonds while displaying chemoselecti

The transition-metal-free intramolecular C-H amination of sulfamate esters using iodine oxidants, tert-butyl hypoiodite (t-BuOI) and N-iodosuccinimide (NIS) is reported. A method using NIS was also successfully applied to the oxidative cyclization of N-alkylsulfamides.

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
Oxidative cyclization of sulfamate esters using NaOCl - A metal-mediated Hoffman-L?ffler-Freytag reaction
Zalatan, David N.,Du Bois
experimental part, p. 143 - 146 (2009/06/06)
Intramolecular C-H amination with sulfamate esters occurs under the action of dinuclear Rh catalysts and iodine(III) oxidants, and has recently emerged as a powerful tool for synthesis. Insights gained through mechanistic studies of this process suggest t
