intermediates under mild reaction conditions has been an important challenge with attractive prospective in organic synthesis. In this work, we show the efficient combination of an electrophilic iron catalyst with a lithium Lewis acid for the functionalization of strong Csp3−H bonds of cyclic and linear alkanes by the activation of commercially available ethyl diazoacetate (EDA). The reaction proceeds with good
在温和的反应条件下通过卡宾铁中间体对强C sp 3 -H键的修饰一直是重要的挑战,在有机合成中具有广阔的前景。在这项工作中,我们显示了亲电铁催化剂与路易斯酸锂的有效结合,用于通过活化市售重氮乙酸乙酯(EDA)活化环状和线性烷烃的强C sp 3 -H键。在温和的反应条件下(40°C),反应以良好的收率进行,不需要大量过量的底物。另外,在具有挑战性的脂族烯烃的环丙烷化中观察到优异的活性。
