FIELD: chemistry.

SUBSTANCE: invention relates to novel fungicidally active 5-fluoropyrimidines of general formula I. In compounds of formula , R¹ is -N(R³)R⁴; R² is -OR²¹; R³ is: H; C₁-C₆-alkyl, optionally substituted with 1-3 groups R⁵; C₂-C₆-alkenyl, optionally substituted with 1-3 groups R⁵; a 5- or 6-member heteroaromatic cycle, selected from a group consisting of furanyl, pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, thiazolyl, thiadiazolyl, oxazolyl, isoxazolyl, triazolyl; wherein each heteroaromatic cycle is optionally substituted with 1-3 R²⁹ groups; 3H-isobenzofuran-1-oyl; -C(=O)R⁶; -C(=S)R⁶; -C(=S)NHR⁸; -(=O)N(R⁸)R¹⁰; -OR⁷; -P(O)(OR¹⁵)₂; -S(O)₂R⁸;-SR⁸; -Si(R⁸)₃; -N(R⁹)R¹⁰; -(CHR²⁴)_mOR²⁹ or -C(=NR¹⁶)SR¹⁶; where m equals an integer from 1 to 3; R⁴ is: H; C₁-C₆-alkyl, optionally substituted with 1-3 R⁵ groups; or -C(=O)R⁶; alternatively, R³ and R⁴ together can form: a 5- or 6-member saturated or unsaturated cycle containing 1-2 heteroatoms selected from N and O, where each cycle can be optionally substituted with 1-3 R¹¹ groups; =C(R¹²)N(R¹³)R¹⁴ or =C(R¹⁵)OR¹⁵. The rest of the radicals are given in the claim.

EFFECT: obtaining novel fungicidally active 5-fluoropyrimidines of general formula I.
