Alpha, beta-dialkyl conjugated nitriles are disclosed which have interesting perfumistic qualities. These materials have the general structural formula ##STR1## where R is an aliphatic hydrocarbon radical of about 1 to 15 carbon atoms having no unsaturation in conjugated relationship with either the nitrile unsaturation or the alpha, beta-olefinic unsaturation, and R' and R" are the same or different aliphatic hydrocarbon radicals meeting the description of R, or R' and R", taken together, form a cycloaliphatic radical having about 6 to 15 carbon atoms. They are produced by the reaction of the appropriate aliphatic nitrile and ketone under the influence of a basic catalyst.
披露了具有有趣香气特质的α,β-二烷基共轭腈。这些材料具有一般的结构式##STR1##其中R是大约1到15个碳原子的脂肪烃基,与腈不饱和度或α,β-烯烃不饱和度之一没有共轭关系,而R'和R"是满足R描述的相同或不同的脂肪烃基,或者R'和R"一起形成大约6到15个碳原子的环脂肪基。它们是通过在碱性催化剂的影响下,适当的脂肪腈和酮的反应产生的。
