The cleavage of the title compounds () in methanolic potassium hydroxide gives mixtures of olefins and α-methoxyolefins in good yields. The ratio of the products is dependent on the size of the carbocydic ring. The mechanism proposed involves cleavage of to the corresponding allylic chloride (). Solvolysis of the chloride gives the α-methoxyolefin. Alternatively, oxidative addition of to Pd(0) generates
标题化合物()在甲醇氢氧化钾中的裂解以良好的收率得到烯烃和α-甲氧基烯烃的混合物。产物的比例取决于碳环的大小。提出的机理涉及裂解成相应的烯丙基氯()。氯化物的溶剂分解得到α-甲氧基烯烃。或者,氧化成Pd(0)可生成新的π-烯丙基络合物,该化合物在随后裂解后可提供烯烃产物。
