Trifluoroacetohydroximoyl bromide etherate (1) reacted with an excess of malononitrile in the presence of sodium methoxide, giving a fused isoxazolopyridine 3, participated by two molecules of malononitrile, along with the conventional isoxazole 2.Similar concomitant formation of 7 and the fused pyrazolopyridines 8 was also recognized from the hydrazonoyl bromides 6 and their product ratio was found to depend on the reaction conditions, particularly on the concentration of malononitrile used.

The synthesis of 1,1-dicyano-2-chloro-2-trifluoromethylethylene was realized.Its reaction with nucleophilic reagents (alcohols, amines, 1,3,3-trimethyl-2-methyleneindoline, and dimethylaniline) leads to products from substitution of the chlorine atom.For 1,1-dicyano-2-(p-dimethylaminophenyl)ethylenes with various substituents at position 2 a correlation was obtained between the absorption frequency in the electronic spectrum and the ?I and ?R constants of the substituents.
