开发了一种 Ce 催化的策略,通过在室温下光氧化裂解 C-C 双键来生产联芳基甲酮。该反应在空气下进行,表现出高活性和官能团耐受性。基于实验观察,还提出了协同的 Ce/ROH 催化机制。该协议应该是第一个成功的 Ce 催化烯烃以空气为氧化剂的光氧化反应,这将为开发新型 Ce 催化光化学合成工艺提供灵感。

In this study, a one-pot two-step Pd-catalyzed reductive eliminate between acetyl naphthalene derivatives, tosylhydrazide, and arylhalide, affording substituted 1(or 2)-(1-phenylvinyl)naphthalene in moderate-to-excellent yields, was reported. Notably, solvent played a crucial role in the coupling of 1-acetyl naphthalene derivatives (toluene) or 2-acetyl naphthalene derivatives (1, 4-dioxane) as starting
