Conclusions 1. High trans-stereospecificity has been shown in the addition to cyanoacetylene of: a) secondary aliphatic amines, with cooling, and b) under the usual conditions with sterically hindered amines, phosphines, mercaptan, and arsine, and also with amines with reduced positive mesomeric capacity of the nitrogen atom. 2. The cis-products of the addition to cyanoacetylene of aziridines, diaziridine, imidazole, di-tert-butylamine, phosphines, and arsine are highly resistant to cis-trans isomerization. In cis-β-di-tert-butylaminoacrylonitrile, amide-type conjugation is sterically hindered.
