This paper presents a versatile reagent for epoxide cleavage. The allyltin tribromide could act as a novel and easily prepared allylation reagent and halide atom donor to convert epoxides to the corresponding homoallyl alcohols and halohydrins in high yields with excellent regioselectivities under mild reaction conditions, respectively. It could also act as a Lewis acid to catalyze the ring opening
本文提出了一种用于环氧化物裂解的通用试剂。三溴化烯丙基锡可以作为一种新颖且易于制备的烯丙基化试剂和卤化物原子供体,分别在温和的反应条件下以高收率将环氧化物高产率地转化为相应的烯丙基醇和卤代醇。它也可以作为路易斯酸来催化环氧化物与醇的开环反应。
