FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing substituted 2-ylidene-1,3-dithiolanes of general formula 
, where R=H, X=CN; R=CH3, X=CN; R=H, X=CONH2; R=CH3, X=CONH2. Method involves reaction of a methyleneactive compound with carbon disulphide in the presence of sodium ethoxide, addition of dichloroalkane to the obtained mixture, boiling for 10–15 minutes and dilution of the reaction mass with water.
EFFECT: disclosed is a method of producing substituted 2-ylidene-1,3-dithiolanes.
