A three-component 1,2-aminoarylation of vinyl ethers, enamides, ene-carbamates and thioethers by synergistic photoredox nickel catalysis is reported. 2,2,2-Trifluoroethoxy carbonyl protected α-amino-oxy acids are used as amidyl radical precursors. anti-Markovnikov addition the to alkene Ni-mediated radical/transition metal cross over lead corresponding product. The cascade, which can be conduct...

С использованием «квантовой теории атомов в молекулах» (QTAIM) определены интегральные электронные характеристики (заряды и объемы) функциональных групп NH, C(O)H, SH, CH, OH, CHOH, CHCOOH, COOH, CHC(O)NH, CHS, СН, CH(CH)-OH C(O)NH десяти молекул α-аминокислот такого же количества α-аминоальдегидов. Показано, что преобразование структуры (замена СООН на C(O)H) снижает заряд заместителя аминогру...

in order to evaluate the effect of some qualitative traits of sugar beet (beta vulgaris l.) under irrigation water quality and different types of fertilizers, a field experiment arranged as split plot in rcbd design with three replications at research station of shahrekord university in 2013. the main factor include irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigat...

Palladium-catalyzed decarboxylative alpha-allylation of nitriles readily occurs with use of Pd(2)(dba)(3) and rac-BINAP. This catalyst mixture also allows the highly regiospecific alpha-allylation of nitriles in the presence of much more acidic alpha-protons. Thus, the reported method provides access to compounds that are not readily available via base-mediated allylation chemistries. Lastly, m...

Sulfur-containing nitriles have important research value in the life sciences due to their diverse biological activities resulting from the sulfur and cyano functional groups. Herein, a copper-catalyzed cyanothiolation of N-tosylhydrazones with thiocyanates to generate a-arylthioalkanenitriles bearing sulfur-substituted quaternary carbon center atoms has been described. This novel protocol invo...
