Reaction of hexacyanocyclopropane with aliphatic amine hydroiodides gives corresponding pentacyano-2-propen-1-ides and cyanogen iodide, whereas with aromatic amine hydroiodides unsubstituted and ring-substituted N-(tricyanovinyl)anilines or N,N-dialkyl-4-(tricyanovinyl)anilines, malononitrile, and iodine are formed.

Reaction of hexacyanocyclopropane with aromatic amines yields N- and C-tricyanovinylanilines. A mechanism of this reaction is proposed on the basis of stoichiometric ratios in the reactions of hexacyanocyclopropane and tetracyanoethylene oxide with aromatic amines.

The reaction between arylazo p-tolyl sulfones 1a-f (Ar-N=N-SO2-p-Tol) and the potassium salts of some active-methylene compounds (CH2XY: X, Y = CN, COOEt) represents an example of unprecedented behaviour of azosulfones and effectively leads, depending on the nucleophile, to either unsymmetrical (6-8) or symmetrical (9) tetrasubstituted ethylenes.Of particular interest is the possibility to synthesize, in high yields and mild conditions, polarysed ethylenes some of which are otherwise not easily accessible.A mechanism involving successive condensation processes is supported by experimental evidence.
Mechanism of the Reaction of 1,3-Diaryltriazenes with Tetracyanoethylene in the Presence of Acetic Acid
Mitsuhashi, Tsutomu
, p. 1495 - 1500 (2007/10/02)
The mechanism for the reaction of 1,3-diaryltriazenes with tetracyanoethylene (TCNE) in the presence of acetic acid, giving Schiff's bases and arylhydrazonomalonitriles, has been investigated.The intermediacy of arylazomalononitriles was confirmed by crossover experiments using an arylamine different from the component of the triazene.The route to the azo compounds via TCNE-triazene adducts had already been established by a tracer experiment using an 15N-labelled triazene.However, the crossover experiments, as well as the result of the reaction of a triazene with the TCNE-2,6-dimethylaniline adduct, revealed an alternative route via TCNE-ArNH2 adducts in the presence of acetic acid.
