Abstract: | The dehydration of farnesols or nerolidols is similar to that of geraniol and nerol or linalool. It yields a mixture of hydrocarbons including trans-β-farnesene, two allofarnesenes, α-curcumene, α-, β- and γ-bisabolenes, and triterpenes. The triterpenes result from dienisation of β-farnesenes or α-farnesenes with β-farnesenes, or dimerization of allofarnesenes. |
