    摘要: Described are 1-phenyl-1-cyano-C.sub.5 -C.sub.7 alkanes defined according to the structure: ##STR1## wherein R.sub.1 and R.sub.2 each represents hydrogen or methoxy with the proviso that when R.sub.1 is methoxy, R.sub.2 is hydrogen and when R.sub.2 is methoxy, R.sub.1 is hydrogen; and wherein X is C.sub.3 -C.sub.5 straight chain or branched chain alkylene and uses thereof in augmenting, enhancing or modifying perfume compositions, perfumed articles and colognes. Also described is a process for preparing such 1-phenyl-1-cyano-C.sub.5 -C.sub.7 alkanes by means of reacting benzyl cyanide with an aldehyde or ketone and then hydrogenating the resulting product using a supported palladium catalyst.
