Ma, Qiang;Song, Jinshuai;Zhang, Xun;Jiang, Yu;Ji, Li;Liao, Saihu research published 《 Metal-free atom transfer radical polymerization with ppm catalyst loading under sunlight》, the research content is summarized as follows. Organocatalytic atom transfer radical polymerization (O-ATRP) is recently emerging as an appealing method for the synthesis of metal-free polymer materials with well-defined microstructures and architectures. However, the development of highly effective catalysts that can be employed at a practical low loading are still a challenging task. Herein, we introduce a catalyst design logic based on heteroatom-doping of polycyclic arenes, which leads to the discovery of oxygen-doped anthanthrene (ODA) as highly effective organic photoredox catalysts for O-ATRP. In comparison with known organocatalysts, ODAs feature strong visible-light absorption together with high molar extinction coefficient (ε _455nm up to 23,950 M^-1 cm^-1), which allow for the establishment of a controlled polymerization under sunlight at low ppm levels of catalyst loading.

Category: esters-buliding-blocks, Benzyl methacrylate, also known as Benzyl methacrylate, is a useful research compound. Its molecular formula is C11H12O2 and its molecular weight is 176.21 g/mol. The purity is usually 95%.
Benzyl methacrylate is a chemical compound that belongs to the group of benzyl compounds. It has a copolymer structure with methyl ethyl methacrylate (MEMA) and hydroxyl groups. Benzyl methacrylate is produced by polymerization of benzyl chloride with allyl carbonate in the presence of radiation, forming a polymeric matrix. The morphology of this copolymer depends on the length of the benzyl chains and the concentration of MEMA., 2495-37-6.

Lv, Honggui;Kang, Huiying;Zhou, Biying;Xue, Xiaosong;Engle, Keary M.;Zhao, Dongbing research published 《 Nickel-catalyzed intermolecular oxidative Heck arylation driven by transfer hydrogenation》, the research content is summarized as follows. The regioselectivity (γ-selectivity vs. δ-selectivity) and pathway selectivity (hydroarylation vs. oxidative Heck coupling) of a directed Ni-catalyzed alkene arylation can be controlled by judicious tuning of the coordination environment around the nickel catalyst via optimization of an appropriate phosphine ligand and directing group. In this way, the Ni(0)-catalyzed oxidative Heck arylation that relies on transfer hydrogenation of an acceptor olefin RNHC(O)XYCH=CHR¹ (R = quinolin-8-yl; X = CH₂, CHMe, CHPh, C(Me)₂; Y = CH₂, CHMe, CHPh, C(Me)₂; R¹ = H, Me, Ph) is developed with excellent E/Z selectivity and regioselectivity.

Luo, Bingcai;Zhang, Yubao;Chen, Ying;Huo, Jianqiang research published 《 Photocatalytic conversion of arylboronic acids to phenols by a new 2D donor-acceptor covalent organic framework》, the research content is summarized as follows. In this research, synthesized a two-dimensional (2D) D-A type COF (BTT-BTDDA-COF) based on alternating connections of benzotrithiophene (BTT) and 4,4′-(2,1,3-benzothiadiazole-4,7-diyl)dianiline (BTDDA) units, with a wide visible light absorption range and good photoelec. response characteristics was reported. In the photocatalytic conversion of arylboronic acid to phenol, BTT-BTDDA-COF exhibits high catalytic activity, wide substrate applicability and good recoverability. The high-efficiency photocatalytic activity of BTT-BTDDA-COF was reasonably attributed to the electron push-pull effect between the donor and acceptor units, which significantly improves the transfer and separation of carriers, which leads to the expansion of the visible light absorption range. The above results show the practicability of COFs material design and provide a new idea for the application of the new D-A COF catalyst in photocatalytic organic conversion.
