The influence of organic additives in the nickel-plating sulfate electrolyte on the pos sibility of obtaining shiny coatings is investigated. The presence in the structure of the additive of trichloramide fragments and substituents containing a thiocarbonyl group-a residue of thiourea or rubeanoic acid, allows to obtain shiny nickel coatings without the introduction of additional reagents.

The effect of trichloroethylamides on the possibility of obtaining shiny coatings in a nickel-plating sulfate electrolyte is investigated. The presence of trichloramide fragments and substituents containing a thiocarbonyl group in the structure of the additive makes it possible to obtain shiny and semi-shiny nickel coatings without the introduction of additional reagents

The sense of bis(2-chloropropenyl)sulfide heterocyclization at its interaction with sulfur, selen and tellur in the hydrazine hydrate–KOH system has been studied. The suggest plausible mechanism of different heterocycles formation is discussed.

A new efficient synthesis of diethylditelluride has been developed, which simultaneously allows the processing of polychlorethylen
