Developing olefin isomerization reactions to reach kinetically controlled Z-alkenes is challenging because formation of trans-alkenes is thermodynamically favored under the traditional catalytic conditions using acids, bases, or transition metals as the catalysts. A new synthesis of Z-alkenes from Rh(I)-catalyzed olefin isomerization of β,γ-unsaturated ketones to α,β-unsaturated ketones was developed
发展烯烃异构化反应以达到动力学控制的Z-烯烃是具有挑战性的,因为在使用酸,碱或过渡金属作为催化剂的传统催化条件下,热力学上有利于反式烯烃的形成。开发了一种由Rh(I)催化的将β,γ-不饱和酮异构化为α,β-不饱和酮的新方法合成Z-烯烃的方法,为获得各种Z-烯酮提供了一种简便而有效的方法。
