and ruthenium has led to reactivity and selectivity levels that were previously inaccessible. Here we show that molybdenum monoaryloxide chloride complexes furnish higher-energy (Z) isomers of trifluoromethyl-substituted alkenes through cross-metathesis reactions with the commercially available, inexpensive and typically inert Z-1,1,1,4,4,4-hexafluoro-2-butene. Furthermore, otherwise inefficient and
催化剂控制的立体选择性烯烃复分解过程的发展一直是化学领域的一项关键进展。在基于钼、钨和钌的配合物中掺入适当的配体导致了以前无法达到的反应性和选择性水平。在这里,我们表明,钼单芳氧基氯化物配合物通过与市售、廉价且通常惰性的 Z-1,1,1,4,4,4-六氟化合物的交叉复分解反应提供三氟甲基取代烯烃的高能 (Z) 异构体。 -2-丁烯。此外,用 Z-1,2-二氯乙烯和 1,2-二溴乙烯进行的低效和非立体选择性转化可以以显着提高的效率和 Z 选择性实现。使用这种钼单芳氧基氯化物复合物能够合成具有代表性的生物活性分子和医药相关化合物的三氟甲基类似物。在密度泛函理论计算的帮助下阐明了所观察到的活性和选择性水平的起源,这与先前提出的原则相矛盾。
