Although chlorocyanoacetylene is converted into an amide in sulphuric acid, cyanoacetylene itself is not. Nevertheless, both nitriles undergo the Ritter reaction with olefins and alcohols. N-(1,1-Dimethyl-2-chloroethyl)-propiolamide, one of the Ritter reaction products, gives an oxazoline on treatment with alkoxide, with accompanying addition of the alkoxide to the triple bond.
尽管氯氰基乙炔在硫酸中转化为酰胺,但氰基乙炔本身不是。尽管如此,两种腈都与烯烃和醇类进行了Ritter反应。Ritter反应产物之一N-(1,1-二甲基-2-氯乙基)-丙酰胺酰胺在用醇盐处理时伴随着将醇盐加成到三键上而得到恶唑啉。
