alcohols, by meta‐C−H activation of benzylsulfonyl esters is described. In addition, α,β‐unsaturated aldehydes were generated by in situ olefination and deprotection of allyl benzyl ethers. These new functionalizations at the meta‐position of an arene have also been successfully implemented in benzylphosphonate, phenethyl carbonyl, and phenethylsulfonyl ester scaffolds. Key to these successful new functionalizations
到扩大的范围的元-functionalization,有效地形成β -芳基醛和酮的,使用烯丙基醇,通过基于嘧啶模板元苄酯的-C-H活化进行说明。此外,α,β-不饱和醛是通过烯丙基苄基醚的原位烯烃化和脱保护而生成的。元上的这些新功能芳烃的位置也已成功地用于苄基膦酸酯,苯乙基羰基和苯乙基磺酰基酯支架中。这些成功的新功能化的关键是通过接受从金属到嘧啶环的能量低的π轨道的电子云来创建正电的钯中心,它有利于烯丙醇与金属中心的配位。
