Abstract:
This report describes an electron-rich carbazole catalyst for the photogeneration of radicals from a range of alkyl halides. Mechanistic studies showed that two distinct catalytic pathways could be accessed, with the carbazole capable of serving as an effective photoredox catalyst under direct irradiation or as a halogen-bonding photocatalyst in the presence of suitable halogen-bond donors. Both strategies enabled radical alkylation reactions with comparable efficiencies, providing alternative options depending on the desired starting substrate and irradiation wavelength.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
