In this work, we report a thorough investigation of the reaction of phenols with aryldiazoacetates. Mechanistic studies using different spectroscopic methods and theoretical calculations suggest a hydrogen bond between phenol and aryldiazoacetates, which can be modulated by the phenol acidity. The pK_A of phenol and therefore the hydrogen bond plays an important role in a subsequent photoinduced proton transfer reaction to give the formal O–H functionalization product of phenols.

通过质子转移用苯酚对重氮乙酸乙酸酯进行光化学OH功能化。

在这项工作中，我们报告了对酚与芳基重氮乙酸酯反应的彻底研究。使用不同光谱方法进行的机械研究和理论计算表明，苯酚和芳基重氮乙酸酯之间存在氢键，该氢键可通过酚的酸度进行调节。苯酚的p K _A以及因此的氢键在随后的光致质子转移反应中起重要作用，从而得到苯酚的正规O–H官能化产物。
