I. published the artcile< Molecular Design of Donor-Acceptor-Type Organic Photocatalysts for Metal-free Aromatic C-C Bond Formations under Visible Light>, Application of C7H3FIN, the main research area is mol Donor Acceptor organic photocatalysts metal free aromatic carbon.

Metal-free and photocatalytic radical-mediated aromatic C-C bond formations offer a promising alternative pathway to the conventional transition metal-catalyzed cross-coupling reactions. However, the formation of aryl radicals from common precursors such as aryl halides is highly challenging due to their extremely high reductive potential. Here, we report a structural design strategy of donor-acceptor-type organic photocatalysts for visible light-driven C-C bond formations through the reductive dehalogenation of aryl halides. The reduction potential of the photocatalysts could be systematically aligned to be -2.04 V vs. SCE via a simple heteroatom engineering of the donor-acceptor moieties. The high reductive potential of the mol. photocatalyst could reduce various aryl halides into aryl radicals to form the C-C bond with heteroarenes. The design ability of the mol. photocatalyst further allowed the synthesis of a high LUMO (LUMO) polymer photocatalyst by a self-initiated free radical polymerization without compromising its LUMO level.

In this report we describe a simple synthesis of mercaptobenzonitriles from the reaction of fluorobenzonitriles with Na2S in DMF at room temperature and following direct treatment with Zn/HCl. Significantly, 2- and 4-fluorobenzonitriles substituted with chlorine or bromine, but not iodine, undergo selective substitution of fluorine at room temperature to yield synthetically useful halo-substituted mercaptobenzonitriles.

Dakarapu, Rambabu; Falck, John R. published the artcile< Stereospecific Stille Cross-Couplings Using Mn(II)Cl2>, Application In Synthesis of 887266-99-1, the main research area is manganese chloride stereoselective Stille cross coupling reaction catalyst; organotin aryl iodide stereoselective Stille coupling reaction.

Cross-coupling reactions are a staple in organic synthesis, especially for C-C bond formation with sp- and sp2-carbon electrophiles. In recent years, the range of accessible C-C bonds has been extended to stereogenic centers which expedites access to greater mol. complexity. However, these reactions predominantly depend upon late transition metal (LTM) catalysts whose cost, toxicity, and/or environmental impact have come under increasing scrutiny and governmental regulation. Here, we report Mn(II)Cl2 complexes alone, or with assistance from copper, catalyze the stereospecific cross-coupling of α-alkoxyalkylstannanes with organic electrophiles with complete retention of configuration.

Gao, Yuan; Sachinthani, K. A. Niradha; Zheng, Chao; Jarrett-Wilkins, Charlie; Johnston, Andrew; Sun, Meng-Jia; Najarian, Amin Morteza; Wang, Ya-Kun; Saidaminov, Makhsud I.; de Arquer, F. Pelayo Garcia; Seferos, Dwight S.; Hoogland, Sjoerd; Sargent, Edward H. published the artcile< Self-Aligned Non-Centrosymmetric Conjugated Molecules Enable Electro-Optic Perovskites>, Safety of 3-Fluoro-4-iodobenzonitrile, the main research area is self aligned non centrosym conjugated mol electro optic perovskite.

Solution-processed organic electro-optic (EO) chromophores are well suited for integration in optical modulators on silicon photonics chips. They contain highly conjugated mols. with polar functional groups offering large dipoles and a large nonlinear optical response. However, these mols. form centrosym. aggregates that hinder poling efficiency and the resultant macroscopic EO response. Furthermore, at elevated temperatures, the alignment of poled mols. can be lost, leading to a reduction in the EO response. Inorganic EO materials exhibit excellent thermal stability but lower performance. Here 2D metal halide perovskite scaffolds that align EO mols. are reported. The approach heralds a material design strategy that combines the features of organic and inorganic EO materials. The EO material exhibits promising thermal stability with a performance approaching that of organic EO materials. Anchor diammonium non-centrosym. mols. are anchored inside a 2D metal halide perovskite scaffold, thereby avoiding aggregation. The authors lever the thermal stability of this compound and pole the organic mols. under an elec. field at 533 K. The 2D perovskites exhibit a macroscopic EO coefficient of 68 pm V-1-a twofold increase over LiNbO3. D. functional theory calculations show that the in-plane alignment of the mol. dipole moments can account for the EO response.

When the addition had ended, the mixture was stirred further at -78 C. for another 75 min. 15 ml (64.8 mmol) of triisopropyl borate were then added dropwise. The mixture was then stirred at -78 C. for a further 15 min, before the cold bath was removed and the reaction mixture was allowed to warm to RT. After 3 h at RT, 80 ml of 2 M hydrochloric acid were added and the mixture was stirred intensively at RT for 20 min. Thereafter, it was diluted with approx. 400 ml of water. The phases were separated and the aqueous phase was extracted three times with approx. 150 ml of ethyl acetate each time. The combined organic extracts were washed successively with water and saturated sodium chloride solution. After drying over anhydrous magnesium sulfate, the mixture was filtered and the filtrated was concentrated to dryness on a rotary evaporator. 3.68 g (55% of th.) of the title compound were obtained, this being employed for subsequent reactions without further purification. LC/MS (method F, ESIneg): Rt=0.53 min, m/z=164 [M-H]-.
