Unsymmetrical azo compounds: ##EQU1## where (R").sub.3 C-- is tertiary-aliphatic and Z is cyano or a derivative thereof, e.g., 2-t-butylazo-2-cyanopropane; processes for preparing such azo compounds by (a) adding hydrocyanic acid to a preformed hydrazone, ##EQU2## of a ketone to form a hydrazo compound, and oxidizing the hydrazo compound; or (b) oxidizing the hydrazo compound formed by the reaction of a t-aliphatic hydrazine with hydrogen or alkali metal cyanide in water.
非对称偶氮化合物:##EQU1## 其中(R").sub.3 C--为三级脂肪基,Z为氰基或其衍生物,例如2-叔丁基偶氮-2-氰丙烷;通过以下方法制备这种偶氮化合物:(a)将氰化氢加入预先形成的腙烷,##EQU2## 与酮的反应形成联氮化合物,并氧化联氮化合物;或者(b)将三级脂肪基腙与水中的氢或碱金属氰化物反应形成的联氮化合物氧化。
