C14H26O2, Mr 226.36, 7>p2kPa 140-142 °C, df 0.8730, ng 1.4503, is a colorless liquid with a flowery, warm-woody citrus odor. It is relatively stable in alkali and can, therefore, be used in soap. 

A few alkyl- and aralkyl-substituted aromatic hydrocarbons find limited use in perfumery. Examples include /i-cymene [99-87-6], which is a component of many essential oils and when pure has a weak, citrus odor, as well as diphenylmethane [101-81-5] which has an odor like geranium ...

Conversion of teipenes to aldehyde derivatives by hydroformylation has been studied extensively. Hydroformylation of limonene is practiced commercially by Celanese [34]. Limonene aldehyde has a citrus odor and is used in soaps and lotions. Spirambrene is manufactured by Givaudan and Vigrai by hydroformylation of 2-carene [35, 36]. Tollens reaction of the resulting aldehyde gives a diol which is converted to the acetal with acetone. Spirambrene has a woody, spicy odor and is a component of perfumes. 

Dihydronootkatone (17), which shows that citrus odor possesses antitermite activity, was also treated in A. niger to obtain 115-mono- (18) and lll -dihydroxylated products (19) (the ratio 115 and 11/ = 3 2). On the other hand, Aspergillus cellulosae reduced ketone group at C2 of 17 to give 2a- (20) (75.7%) and 2p-hydroxynootkatone (21) (0.7%) (Furusawa et al., 2003) (Figure 20.11). Tetrahydronootkatone (22) also shows antitermite and mosquito-repellant activity. It was incu-... 

Undecanal can be prepared from 1-decene, also employing the Rh(BIPHEP-HOS) catalyst (Table 6.1, entry 4). Similarly, a water-soluble Rh(TPPTS) complex was successfully synthesized (Scheme 6.6, w = 2) [54]. w-Regioselectivities up to 99% were noted in ionic liquids [55]. With its flowery-waxy-citrus odor, it gives the impression of freshness. Therefore the compound is the prototype of perfumery aldehydes and is widely used in different aroma applications. 2-Methyldecanal, which might be formed as isomeric side product, has an aldehydic, citrus-peel-like, waxy-green odor. It is used in perfumery to refresh green and citrus nuances.
