FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a compound of formula (I), where X is selected from S, Se, values R₁ R₂, R₃, R₄ and R₅ are defined in the claims. Method involves reaction of a compound of formula (IV), where X is selected from S and Se, m is equal to 1 or 2, R₁ is as defined for compound (I), and if m is 1, R₂₁ is H, if m is 2, R₂₁ is selected from alkyl, aryl and alkylaryl groups, with a compound of formula (V), where R₂, R₃, R₄ and R₅ are as defined for the compound of formula (I), by irradiation with radiation with wavelength from 200 to 800 nm in the presence of at least one compound containing at least one functional group, selected from alcohol, carboxyl, thioether and selenium ether functional groups, which is a compound of formula (VI), where X' is selected from S or Se, p and t independently represent 0 or 1, q, r and s independently represent 0–10, provided that p + r + t is greater than or equal to 1, and if p is not equal to 0, then q + s is not equal to 0, R₂₂ is selected, if p is 0, from H and alkyl, aryl and arylalkyl groups, and if p is 1, from alkyl, aryl and arylalkyl groups, and R₂₃, R₂₄, R₂₅, R₂₆ and R₂₇ are independently selected from H and alkyl, aryl and alkylaryl groups.

EFFECT: present invention provides an alternative to existing methods, wherein the addition of a compound of formula (VI) has a positive effect on conversion, output and selectivity parameters.
