N-doped graphene used as an efficient electron donor of iron catalysts for CO hydrogenation can achieve a high selectivity of around 50% for light olefins, significantly superior to the selectivity of iron catalysts on conventional carbon materials, e.g. carbon black with a selectivity of around 30% at the same reaction conditions.

A tin- and halide-free, visible-light photoredox-catalyzed Giese reaction was developed. Primary and secondary α-amino radicals were generated readily from amino acids in the presence of catalytic amounts of an iridium photocatalyst. The reactivity of the α-amino radicals has been evaluated for the functionalization of a variety of activated olefins.

Fluorine-containing organic molecules are expected to be used in various applications, and radical reactions considered useful synthetic methods. Visible-light-induced using photoredox catalysts continue investigated their application the synthesis of fluorinated compounds has been reported. We have developed organocatalytic perfluoroalkylation through environmentally friendly visible-light-dri...

An efficient, unique, and convenient method for the iodoamidation of olefins with chloramine salts and I(2) in aqueous media is described. This method was applicable to a wide range of olefins, including aromatic, aliphatic, and electron-deficient olefins.

A systematically varied series of conformationally restricted ketones, readily prepared from N-acetyl-D-glucosamine, were tested against representative olefins as asymmetric epoxidation catalysts showing useful selectivities against terminal olefins and, in particular, typically difficult 2,2-disubstituted terminal olefins.
