METHOD OF PRODUCING TERTIARY AMINES CONTAINING ETHENYLBENZYL SUBSTITUTES Russian patent published in 2020 - IPC C07C209/08 C07C211/27 C07C211/45 C07D295/02 C07D295/88 C07D295/73 C07D295/13 C07D245/04 C07D285/38 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to methods of producing compounds of formula (I) or (II) or mixtures of their isomers. In formula (I) or (II), R¹, R², R³ and R⁴ independently represent -H, -Alk, -Hal, -OH, -OAlk, -OAr, -SAlk, -SAr, -NR₂; R is -Alk, -AlkN(Alk)₂, -AlkN(Ar)₂, -AlkNAlkAr, -AlkOH, -AlkOAlk, -AlkOAr, -AlkSAlk, -AlkSAr, -Ar; R' and R'' independently represent -Alk-, -Alk(NAlk)-, -Alk(NAr₂)-, -Alk(NAlkAr)-, -Alk(OH)-, -Alk(OAlk)-, -Alk(OAr)-, -Alk(SAlk)-, -Alk(SAr)-, -Ar-; Alk is C1-C16 alkyl, C3-C16 cycloalkyl, C2-C16 alkenyl, C2-C16 alkynyl, Ar is phenyl, Hal is a halogen selected from -Cl, -Br, -I. Methods involve reacting corresponding halides , where Hal is halogen, selected from -Cl, -Br, -I with corresponding amine of formula or in inert atmosphere in two-phase water-organic system, in an alkali metal carbonate medium in the presence of an antioxidant and a catalyst based on ammonium or phosphonium salts.

(I) (II).

EFFECT: high output of tertiary amines of formula (I) or (II) or mixture of isomers thereof to 80–90 %, conversion of starting products to 99–100 %, reducing the process time to 2 hours and eliminating the need for labor-consuming and resource-consuming methods of separating and cleaning products.
