Abstract:
A mild and efficient dynamic kinetic resolution (DKR) of amines was achieved by combining visible-light-induced photoredox catalysis and enzyme catalysis. This dual catalytic system was appropriate for both monoamines and 1,4-diamines.

Abstract:
Visible-light photoredox catalysis offers a distinct activation mode complementary to thermal transition metal catalyzed reactions. The vast majority of photoredox processes capitalizes on precious metal ruthenium(II) or iridium(III) complexes that serve as single-electron reductants or oxidants in their photoexcited states. As a low-cost alternative, organic dyes are also frequently used but in general suffer from lower photostability. Copper-based photocatalysts are rapidly emerging, offering not only economic and ecological advantages but also otherwise inaccessible inner-sphere mechanisms,

Abstract:
Atom transfer radical addition of bromonitromethane and 1,2-dibromotetrafluoroethane to alkenes is described. The reaction is performed under blue light irradiation using two catalysts: 4CzIPN and manganese (II) bromide. The cyanoarene photocatalyst serves for the redox activation of starting organic bromide, while the manganese salt facilitates the trapping of the alkyl radical with the formation of the carbon–bromine bond.

Abstract:
Durant ces dernières décennies, la réactivité des donneurs d’électrons organiques de type énamine (DEO) a été largement exploitée dans des réactions de réduction par transfert électronique. De part leurs forts pouvoir réducteur avec des potentiels redox exceptionellement négatifs, les DEOs sont capables de transférer spontanément un ou deux électrons à des substrats organiques, formant ainsi des intermédiaires radicalaires ou anioniques. Cependant, ces DEOs sont toujours utilisés en quantité stœchiométrique, ce qui limite leur compétivité face aux catalyseurs organométalliques et organiques.Le

AbstractSynthetic methodologies based on radical chemistry are efficient and powerful tools for the construction of carbon–carbon and carbon–heteroatom bonds. This chapter highlights the significance of asymmetric catalysis in free-radical reactions. Several asymmetric catalytic principles, ranging from early chiral Lewis acid and organocatalytic activation to recent photoredox and transition-metal-based asymmetric catalytic systems, are discussed.

Abstract:
Abstract In recent years, photoredox catalysis has become a useful strategy in the field of synthetic chemistry because generation of reactive radicals, ionic species, and organometallics under mild reaction conditions can be realized. This review mainly discusses fluorination reactions of carbon skeletons using photoredox catalysis. In addition, seminal works on photochemical hydrogen-atom transfer (HAT) and photocatalyst-free photoinduced electron-transfer systems are also handled. These systems can be applied to fluorination reactions of C—H bonds, C—C bonds, C=C bonds, and appropriate func

Paul J. Chirik at Princeton University reported (Science 2012, 335, 567) an iron catalyst that hydrosilylates alkenes with anti-Markovnikov selectivity, as in the conversion of 1 to 2. A regioselective hydrocarbamoylation of terminal alkenes was developed (Chem. Lett. 2012, 41, 298) by Yoshiaki Nakao at Kyoto University and Tamejiro Hiyama at Chuo University, which allowed for the chemoselective conversion of diene 3 to amide 4. Gojko Lalic at the University of Washington reported (J. Am. Chem. Soc. 2012, 134, 6571) the conversion of terminal alkenes to tertiary amines, such as 5 to 6, with an
