Studies on Russian Economic Development
— The article analyzes the level of import dependence of Russian industry in relation to the supply of intermediate consumption products from China and in general from all countries of the world. The study was carried out during the period of the i

The values of isotropic HFS constantsaN were obtained for nitroxyl radicals (NR) of the piperidine series in hexane and water. The interrelation between rate constants for NR reduction and oxidation reactions, isotropic HFS constantsaN, inductive con

Reaction of cis-α,β-dinitrostilbene (substrate) with morpholine (reagent) in n-hexane leads to cis-α-nitro-β-morpholinostilbene (end product). The process is of first order with respect to the substrate and second order with respect to the reagen
