Photoinduced, Metal-Free Hydroacylation of Aromatic Alkynes for Synthesis of α,β-Unsaturated Ketones via C(sp<sup>3</sup>)–H Functionalization
cross-coupling processes, metal-free cross-coupling reactions for hydroacylation of aromatic alkynes via C(sp3)–H functionalization are still rare and highly desired. Here we report a metal-free reliable approach for the synthesis of α,β-unsaturated ketones (chalcones) via C(sp3)–H functionalizationusing MeCN:H2O as green solvent, Eosin Y as organic photocatalyst, and ambient air as oxidant.

尽管过去十年在通过过渡金属催化交叉偶联过程实现碳-碳键方面取得了显着进展,但通过 C(sp 3 )-H 官能化实现芳香族炔烃加氢酰化的无金属交叉偶联反应仍然很少见并且非常渴望。在这里,我们报告了一种无金属的可靠方法,使用 MeCN:H 2 O 作为绿色溶剂、曙红 Y 作为有机光催化剂和环境空气,通过 C(sp 3 )–H 官能化合成 α,β-不饱和酮(查尔酮)作为氧化剂。更重要的是,该策略可以有效地将各种甲基芳烃和芳香炔转化为所需的产物。该方法具有原子效率高、使用绿色溶剂、不含金属、环境友好、可见光作为可再生能源、与生物活性分子相容等优点。
