Dual photoredox transition-metal catalysis has recently emerged as a powerful tool for making synthetically challenging carbon-carbon bonds under milder reaction conditions. Herein, we report on the visible-light-mediated controlled generation of low-valent cobalt catalyst without the need for a metallic reductant. It enabled C-C bond formation via ene-yne coupling at room temperature. The generality of this dual catalysis is demonstrated via the creation of sizable molecular diversity with the accommodation of several functional groups.

A novel strategy for the expedient construction of CF3-embeded tertiary/quarternary carbon centers was developed by taking advantage of photoredox catalysis. Thanks to a key step of single-electron oxidation, electron-rich gem-difluoroalkenes, which otherwise are essentially reluctant towards F-nucleoplilic addition, now readily participate in this fluoroallylation reaction. Furthermore, this strategy provides an elegant example for the generation, as well as functionalization, of α-CF3-substituted benzylic radical intermediates using cheap and readily available starting materials.

Herein, we report the first example of group transfer radical addition of O-vinylhydroxylamine derivatives onto unactivated alkenes. By utilizing O-vinylhydroxylamine derivatives as both the N- and C-donors, this reaction enables intermolecular carboamination of unactivated alkenes in an atom economical fashion. As the process is initiated through N-radical addition followed by C-transfer, linear carboamination products are afforded. This differs from canonical radical carbofunctionalization of olefins, which typically favors branched product owing to initiation by C-radical addition.

Paragraph 0066-0071, (2017/04/03)
Provided are a synthesis method of an acrylic monomer comprising a naturally derived aliphatic cyclic compound, an acrylic monomer synthesized thereby, and an acrylic pressure-sensitive adhesive composition comprising the same. More particularly, the synthesis method comprises the steps of: preparing a naturally derived aliphatic cyclic compound including a hydroxyl functional group at the end; and having a reaction between the aliphatic cyclic compound and an acrylic acid derivative and synthesizing an acrylic monomer comprising a naturally derived aliphatic cyclic compound. Therefore, the acrylic pressure-sensitive adhesive composition has enhanced adhesive strength when bonded to an object by the acrylic monomer synthesized with a naturally derived aliphatic cyclic compound, and can easily separate a panel from an LCD by being capable of easily detached therefrom. Further, the acrylic pressure-sensitive adhesive composition can have minimized environmental burden by being synthesized with a naturally derived aliphatic cyclic compound.(S10) Step of preparing a naturally derived aliphatic cyclic compound including a hydroxyl functional group at the end(S20) Step of having a reaction between the aliphatic cyclic compound and an acrylic acid derivative and synthesizing an acrylic monomer comprising a naturally derived aliphatic cyclic compoundCOPYRIGHT KIPO 2016
