, p. 60 - 66 (2015)
New catalytic systems with supported bromine- and chlorine-containing copper complexes for selective bromination of alkanes with tetrabromomethane have been proposed. Introduction of donor additives (e.g., low-molecular-weight alcohols) into the reaction increases the activity and stability of these catalysts. The kinetic features of the processes have been investigated. It has been shown that the dependences of the yield of bromodecanes on temperature and concentration of donor additives are both nonmonotonic in character.

Herein we report a practical protocol for the visible-light-induced regiodivergent radical hydropyridylation of unactivated alkenes using pyridinium salts. This approach provides a unified synthetic platform to control the regioselectivity of the synthesis of linear or branched C4-alkylated pyridines. A remarkable selectivity switch from the anti-Markovnikov to the Markovnikov product can be achieved by the addition of tetrabutylammonium bromide. The versatility of this protocol is further demonstrated based on the late-stage functionalization in pharmaceuticals.
METHOD FOR PRODUCING REDUCED HALIDE COMPOUND HAVING UNDERGONE REDUCTION OF CARBON-CARBON UNSATURATED BOND

Paragraph 0178; 0179; 0180; 0181; 0182; 0183, (2019/11/05)
A halide compound having one or more carbon-carbon unsaturated bonds is catalytically reduced with substantially no dehalogenation to produce a reduced halide compound in which at least one of the one or more unsaturated bonds is reduced. Specifically provided is a method for producing a reduced halide compound including steps of: reacting a nickel compound, a zinc compound, and a borohydride compound in a solvent to obtain a reduction catalyst; and subjecting a halide compound having one or more carbon-carbon unsaturated bonds to catalytic reduction in the presence of the reduction catalyst to reduce at least one of the one or more carbon-carbon unsaturated bonds to thereby obtain a reduced halide compound.
