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.
不对称偶氮化合物:##EQU1##其中(R").sub.3 C-是三级脂肪族,Z是氰基或其衍生物,例如2-t-丁基偶氮基-2-氰基丙烷;制备这种偶氮化合物的过程包括:(a)将氢氰酸加入预先形成的酰肼,##EQU2##的酮类化合物,形成一个肼基化合物,然后氧化肼基化合物;或者(b)在水中将t-脂肪族肼与氢或碱金属氰化物反应形成的肼基化合物氧化。
