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.

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.

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
