been prepared and reacted with Grignard and alkyllithium reagents. Acylals from formaldehyde furnished complex reaction mixtures when reacted with both reagents. Acylals of other aldehydes gave reaction mixtures that consisted mainly of an ester, generated by replacing one of the carboxy groups with the organic part of the organometallic reagent, and regenerated aldehyde. The esters were formed in the

A general, facile and eco-friendly iron catalysis enables oxidation of unstrained tertiary aromaticalcohols to ketones through C−C bond cleavage even with H2O2 as the oxidant. Notably, this transformation can tolerate oxidation-labile functional groups. The robustness of this method is further demonstrated on the late-stage oxidation of complex bioactive molecules.
一种通用、简便且环保的铁催化方法,即使使用 H 2 O 2作为氧化剂,也能通过 C−C 键断裂将无张力的叔芳香醇氧化为酮。值得注意的是,这种转化可以耐受氧化不稳定的官能团。该方法的稳健性在复杂生物活性分子的后期氧化中得到进一步证明。
