behaviour of various allylic alcohols in the presence of catalytic amounts of SmCl3 (by heating in 1,2-dichloroethane) has been studied. Diallyl ethers are obtained in many cases in good yields. Mixed allyl alkyl ethers are also prepared if 2–5 equivalents of an aliphatic alcohol is present. The reactions are interpreted as proceeding through a pseudo allylic carbonium intermediate initiated by a preliminary
已经研究了在催化量的SmCl 3存在下(通过在1,2-二氯乙烷中加热)各种烯丙醇的行为。在许多情况下以高收率获得二烯丙基醚。如果存在2-5当量的脂肪醇,也可以制备混合的烯丙基烷基醚。该反应被解释为通过烯丙基羟基与the离子的初步络合引发的拟烯丙基碳中间体进行。
