  as a CO-free and operationally simple protocol. In this reaction, stable and commercially available diethyl dicarbonate serves as a practical alkoxycarbonyl source, and only ethanol and CO2 were produced as byproducts. The utility of this protocol was demonstrated by a gram-scale reaction and the transformation of the ethyl ester moiety.

  (DEAD) together with Oxone or K2S2O8. Substrates such as 2-arylpyridines, pyrrolidinone, acetylindoline, quinoline, and oximes were ethoxycarbonylated with excellent chemo- and regioselectivities. The catalytic reaction is probably initiated by chelation-assisted cyclopalladation of the ortho-C−H bond. Preliminary studies suggested that reactive ethoxyacyl radicals generated from thermal decomposition

  该通讯描述了使用偶氮二羧酸二乙酯 (DEAD) 和 Oxone 或 K2S2O8 的 Pd(OAc)2 催化芳族 CH 键的乙氧基羰基化反应。2-芳基吡啶、吡咯烷酮、乙酰二氢吲哚、喹啉和肟等底物被乙氧基羰基化，具有优异的化学和区域选择性。催化反应可能是由邻位-CH 键的螯合辅助环钯化引发的。初步研究表明，DEAD 热分解产生的反应性乙氧基酰基自由基参与了酯的形成。

  A novel Pd(II)-catalyzed aromatic C-H ethoxycarbonylation with oxaziridine involving C-C bond cleavage is described. Various aromatic 2-phenylpyridines and related compounds as well as aryl ureas can be effectively ethoxycarbonylated. A catalytic cycle involving Pd(II) and Pd(IV) is proposed.

  AbstractA novel palladium‐catalyzed direct alkoxycarbonylation of 2‐arylpyridines, 2‐arylquinolines, benzo[h]quinolines, 2‐phenylpyrimidines, N‐pyrimidine pyrroles and N‐pyrimidine indoles via aromatic CH bond activation and selective CC cleavage of α‐keto esters has been developed. The method has the advantages of wide functional group tolerance, high selectivity, broad range of substrates and good yields.magnified image
