《Photocontrolled Radical Polymerization from Hydridic C-H Bonds》 was written by Stache, Erin E.; Kottisch, Veronika; Fors, Brett P.. Category: esters-buliding-blocks And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:
Given the ubiquity of carbon-hydrogen bonds in biomols. and polymer backbones, the development of a photocontrolled polymerization selectively grafting from a C-H bond represents a powerful strategy for polymer conjugation. This approach would circumvent the need for complex synthetic pathways currently used to introduce functionality at a polymer chain end. On this basis, we developed a hydrogen-atom abstraction strategy that allows for a controlled polymerization selectively from a hydridic C-H bond using a benzophenone photocatalyst, a trithiocarbonate-derived disulfide, and visible light. We performed the polymerization from a variety of ethers, alkanes, unactivated C-H bonds, and alcs. Our method lends itself to photocontrol which has important implications for building advanced macromol. architectures. Finally, we demonstrate that we can graft polymer chains controllably from poly(ethylene glycol) showcasing the potential application of this method for controlled grafting from C-H bonds of commodity polymers. The results came from multiple reactions, including the reaction of Benzyl acrylate(cas: 2495-35-4Category: esters-buliding-blocks)
Benzyl acrylate(cas: 2495-35-4) is a reagent that can be used in the preparation of 2-(Phosphonomethyl)pentanedioic Acid, a selective glutamate carboxypeptidase 2 (GCP-II) inhibitor. It can also be used in the preparation of high refractive index polyacrylates.Category: esters-buliding-blocks
