3-diones 6 along with each of the preceding products. Treatment of the respective (E,Z)-5-(2-aryl-2-oxoethylidene) analogues 3b and 3c with CN− gave 4b and 4c and 2-(arylcarbonyl)-2-methoxy-4-oxopentanedinitriles 7b and 7c, in addition to 3,6-bis[2-(4-chlorophenyl)-1-methoxy-2-oxoethylidene]-1,4-dithiane-2,5-dione 8c, which has been generated from 3c. Reactions of 3c or 3d with NCO− provided 5c or 5d,
