Abstract
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.
