oxidation of hindered alkenes to form linear allylic esters. The combination of palladium(II) benzoate, 4,5-diazafluoren-9-one, and benzoquinone catalyzes the mild oxidation of terminal alkenes with tert-butyl benzoyl peroxide as an oxidant in the presence of diverse functional groups. Selective oxidation of terminal alkenes in the presence of trisubstituted and disubstituted alkenes has been achieved
我们报道了钯催化的受阻烯烃氧化形成线性烯丙基酯。苯甲酸钯(II),4,5-二氮杂芴-9-一和苯醌的组合在多种官能团存在的情况下用叔丁基苯甲酰过氧化物作为氧化剂催化末端烯烃的轻度氧化。已经实现了在三取代和二取代的烯烃的存在下末端烯烃的选择性氧化,并且已经证明了以克规模进行反应的能力。温和的条件和对辅助功能的高度耐受性使该方法适用于复杂分子的合成和衍生化。
