A photocatalytic strategy for the controllable aroylation or diaroylation of allyl sulfones was established using tetrabutylammonium decatungstate (TBADT) as a hydrogen atom transfer (HAT) photocatalyst and aldehydes as radical precursors. By adjusting the substrate ratio, the selectivity of the reaction could be readily tuned and various aroyl groups were installed on allyl sulfones, which furnished
使用四丁基十钨酸铵 (TBADT) 作为氢原子转移 (HAT) 光催化剂和醛作为自由基前体,建立了一种用于烯丙基砜的可控芳酰化或二芳酰化的光催化策略。通过调节底物比例,可以很容易地调节反应的选择性,并将各种芳酰基安装在烯丙基砜上,分别以中等至优异的产率提供 β,γ-不饱和酮和 1,5-二酮。该方法具有条件温和、步骤经济性高、无外加剂、易于获得的资源和广泛的底物范围等特点。
