As a result of the introduction of new technology for recovering sulphur from flash smelting process gas based on methane reduction, a device has been developed for feeding natural gas into the furnace exhaust to ensure effective gas mixing and a sulphur yield close to the equilibrium value.

In the early 2002, asymmetric catalytic activity of chelated chiral borate esters, which possess three B-0 bonds and one B←N coordination bond, toward borane reduction of prochiral ketones was first observed by our research group.

Asymmetric reductive alkylation of malimides is an effective method for the synthesis of optically active N - substituted 5 - alkyl - 4 - benzyloxy - 2 - pyrrolidinones.
