(Laboratory No. 17, Head – DSc V.V. Semenov).
A method of producing composite membranes based on organometal caracass structures MOF-199 and ZIF-8 on inorganic, metalloceramic or polymer supports was developed.

An approach to cyclic peroxides of three different classes, such as tricyclic monoperoxides, bridged tetraoxanes and two isomeric ozonides, based on the heteropolyacids-catalyzed reaction of β, δ-triketones with H2O2 was proposed. This is the first example of preparing an ozonide cycle by peroxidation of carbonyl compounds.

A comprehensive study of the multicomponent process mechanisms has led to a new efficient “one-pot” and “on-water” electrocatalytic method of the cascade transformation of salicylic aldehydes and three malononitrile molecules to substituted tri- and tetracyclic chromeno[2,3-b]pyridine systems with 75-90% yield by substance and 375-450% yield by current.

A new strategy of the one-step synthesis of condensed 1,2,5-selenadiazoles from respective 1,2,5-thiadiazoles was proposed and implemented. It allowed high yields of a number of new heterocyclic systems that are promising as the sources of stable anion radical salts - molecular electricity conductors and magnetics.

A reagent acting as a difluoromethylene-bis equivalent (carbanion) was proposed.
(Laboratory No. 8, Head – DSc А.D. Dilman)
Numerical simulation and cyclic voltammetry methods have shown that the factor determining selectivity of electroreduction of arylhydroxylamines is a previously unknown reaction of hydroxide anion elimination from anion radicals of these compounds that initiates competitive processes of the formation of hydrazo and azo derivatives. Their yield ratio dramatically changes while switching from electroanalytical methods to the electrolysis with the controlled potential.

Unique reactivity of β, δ-triketones in a reaction with H2O2 was discovered: among numerous possible pathways of their transformation one way predominates and leads to previously unknown tricyclic structures containing peroxide, monoperoxyketal and ketal fragments.

For the first time has been found a new type of reactivity of donor-acceptor cyclopropanes, which, under the impact of GaCl3, act as sources of even 1,2- and 1,4-dipoles responsible for the formation of four- and six-membered carbocycles.

Pioneering heterogeneous catalytic oxidation of benzene to phenol by nitrous oxide on a zeolite catalyst (HZSM-5) under supercritical conditions (280-420°C, P = 60-180 atm) was performed. Productivity of HZSM-5 increases 10-fold as compared to a gas phase process, stability of its operation is higher and selectivity (phenol) is above 90%.
