METHOD FOR PRODUCING 4-SUBSTITUTED THIOMORPHOLINES Russian patent published in 2015 - IPC C07D295/03 C07D295/33 C07D295/108

Abstract RU 2551658 C1

FIELD: chemistry.

SUBSTANCE: invention refers to a method for producing N-substituted thiomorpholines of formula (I) wherein divinylsulphide is reacted with an amine substrate (propylamine, aniline, o-, p-toluidine, monoethanolamine, acetamide) in the presence of the catalyst PdCl₂-CF₃COOH-PPh₃ in the molar ratio of divinylsulphide : amine substrate : PdCl₂: CF₃COOH : PPh₃= 10 : 10: (0.3-0.7) : (1.5-3.5) : (0.3-0.7), at a temperature of 55-65°C and an atmospheric pressure for 38-42 h in toluene. In general formula (I), R=CH₃(CH₂)₂, C₆H₅, o-, p-CH₃C₆H₄, C₂H₄OH, CH₃CO.

EFFECT: one-stage high-yield production of the divinylsulhide compounds.
