β-phellandrene does not form a tetrabromide, and indeed we have found no reference in the literature to the formation of such a compound by a conjugated terpene apart from a recent record of a liquid tetrabromide derived from α-terpinene1. During examination of the terpene fractions of the oil from Eucalyptus cneorifolia, we repeatedly isolated a crystalline tetrabromide which had m.p. 110–112° and was
人们普遍认为 β-水芹烯不形成四溴化物,实际上我们在文献中没有发现关于由共轭萜烯形成这种化合物的参考文献,除了最近记录的来自 α-萜品烯的液体四溴化物1 . 在检查来自 Eucalyptus cneorifolia 的油的萜烯部分时,我们反复分离出一种结晶四溴化物,其 mp 为 110-112° 并且是右旋的。用乙酸乙酯重结晶后,熔点升至118-119°,比旋光度几乎为+54°。
