The cyclization reaction of diallyldibutyltin and α- or γ-halo ketones, especially chloro-substituted ketones, effectively proceeds in the presence of a catalytic amount of tetraethylammonium chloride, producing the corresponding 2-allyloxiranes or 2-allyltetrahydrofurans in high yield, respectively. β-Chloro ketones give the corresponding allyl alcohols.
二烯丙基二丁基锡与α-或γ-卤代酮,尤其是氯代酮的环化反应,在催化量的氯化四乙基铵存在下有效进行,分别高产率地生成相应的2-烯丙基环氧乙烷或2-烯丙基四氢呋喃。β-氯代酮则生成相应的烯丙醇。
