o-Iodoxybenzoic acid (IBX), a highly versatile hypervalent iodine(V) reagent, was found to efficiently mediate the dehydrogenation of amines in addition to facilitating the oxidative cleavage of dithioacetals and dithioketals. Through the development of relevant IBX-based protocols, a plethora of useful synthetic intermediates, including imines, oximes, ketones, and aromatic N-heterocycles, were found
发现邻碘苯甲酸 (IBX) 是一种用途广泛的高价碘 (V) 试剂,除了促进二硫缩醛和二硫缩酮的氧化裂解外,还可以有效介导胺的脱氢。通过开发相关的基于 IBX 的协议,发现大量有用的合成中间体,包括亚胺、肟、酮和芳香族 N-杂环,在特别温和的条件下很容易获得。对这些转化的进一步研究导致了对有价值的机械细节的阐明,从而得出结论,它们是通过离子而不是单电子转移 (SET) 途径进行的。
