Abstrakt: The reaction of 2,3-dimercaptoquinoxaline with 3-phenyl-2-propynonitrile (~10 mass % KOH, 20-25°C, 5 h, dioxane) gave the S,S-diadduct (as with unsubstituted acetylene). 2,3-Dimercaptoquinoxaline reacted with 4-alkyl-4-hydroxy-2-alkynonitriles to give 2-cyanomethyl-2-(1-hydroxy-1-alkyl)-1,3-dioxolano[4,5- b]quinoxalines or 3-cyanomethylene-8-imino-2,2,6,6-tetramethyl-1,7-dioxa-4-thiaspiro[4.4]nonane.
