- Novel [4 + 2] cycloaddition reaction of aryl-methylidenemalononitriles to unsaturated chalcogen amides. Synthesis, structure, and properties of triethylammonium 3,5,5-tricyano-1,4,5,6-tetrahydropyridine-2-selenolates and -thiolates
-
Reaction of arylmethylidenemalononitriles with 3-aryl-2-cyanoprop-2- eneselenoamides in the presence of Et3N gave triethylammonium 4,6-diaryl-3,5,5-tricyano-1,4,5,6-tetrahydropyridine-2-selenolates. A similar reaction with cyclohexylidenecyanothioacetamide yields triethylammonium 4-aryl-1,5,5-tri-cyano-3-azaspiro[5.5]undec-1-ene-2-thiolate. Alkylation of the obtained selenolates and thiolates gives 6-(alkylseleno)-2,4-diaryl-1,4- dihydropyridine-3,3,5(2H)-tricarbonitriles and 4-(alkylthio)-2-aryl-3-aza- spiro[5.5]undec-4-ene-1,1,5-tricarbonitriles, respectivelly. The structure of 2,4-di(2-furyl)-6-{[2-(4-methylphenyl)-2-oxoethyl]seleno}-1,4-dihydropyridine-3, 3,5(2H)-tricarbonitrile has been confirmed by the X-ray structural analysis.
