The interaction of 2-fluorobenzaldehyde, cyanoselenoacetamide and Meldrum's acid in the presence of N-methylmorpholine gives 1,2-bis[3-cyano-4-(2- fluorophenyl)-6-oxo-1,4,5,6-tetrahydropyridin-2-yl]di-selane, which also is the product of the reaction of cyanoselenoacetamide with 5-(2-fluorobenzylidene)-2, 2-dimethyl-1,3-dioxane-4,6-dione. The diselane obtained interacts with alkyl halides in the presence of a base, forming the corresponding 4-(2-fluorophenyl)-2-(2-R-methylselanyl)-6-oxo-1,4,5,6-tetra-hydropyridine-3- carbonitriles.
