α-LongifoIene C15H24F1, a tricyclic sesquiterpene hydrocarbon, and phenol were reacted in the presence of boron trifluoride as a catalyst.
1.The reaction was carried out without or with various kinds of solvent under various conditions, changing temperature and time of reaction, but there was no striking difference on the kind of products and their yields.
2. About one-half of α-longifolene was left unreacted with phenol and isomerited to isolongifolene.
3.A dextro-rotatory compound, bp.178-183°C/5mm Hg, was obtained in 30% yield and this was assumed to be longifolyl phenyl ether from the infrared absorption spectrum and other tests.
