thiocyanate to the corresponding radical and promotes subsequent addition to nucleophilic olefins to produce dithiocyanate derivatives under mild conditions with high efficiency. Excellent yields and chemoselectivities together with the environmental-friendly nature of the Fe(III) chloride makes this method an attractive alternative to established methods. The use of ferric chloride makes it quite simple
无水FeCl 3 将硫氰酸钾氧化成相应的自由基,并促进随后与亲核烯烃的加成,在温和条件下高效生产二硫氰酸酯衍生物。优异的产率和化学选择性以及氯化铁 (III) 的环保性质使该方法成为已建立方法的有吸引力的替代方法。三氯化铁的使用使其非常简单、方便和实用。这种新方法具有几个优点,例如高转化率、更清洁的反应曲线、短反应时间以及使用廉价且易于获得的催化剂。
