An efficient protocol for the Cα-H heteroarylation of ethers, amides, and alcohols using air and light under mild conditions is described. The reaction is applicable to a wide spectrum of functional groups. The generation of C-radicals via photoinduced aerobic oxidation of ethers, amides, and alcohols is the key feature of the process. Control experiments suggest a radical pathway for the reaction
描述了在温和条件下使用空气和光对醚、酰胺和醇进行 Cα - H 杂芳基化的有效方案。该反应适用于广泛的官能团。通过醚、酰胺和醇的光诱导有氧氧化产生 C-自由基是该过程的关键特征。对照实验表明该反应的自由基途径。

major limitations of previously reported photoredox-mediated Minisci reactions: (i) use of expensive and potentially harmful non-recyclable photocatalysts, and (ii) requirement of a stoichiometric amount of strong chemical oxidant. Finally, using platinum as a co-catalyst with the carbon nitride allows this light-mediated reaction to generate two value-added products under an anaerobic atmosphere –

A palladium-catalyzed coupling of N-heterocycles with simple alcohols was achieved. The reaction is initiated by peroxide and does not require the use of stoichlometric acid for activation of the heterocycle.
