  Metal-Free Fluorination of C(sp³)–H Bonds Using a Catalytic N-Oxyl Radical

  摘要：

  A direct conversion of C(sp(3))-H bonds to C(sp(3))-F bonds has been developed. In this process, a catalytic N-oxyl radical generated from N,N-dihydroxypyromellitimide abstracts hydrogen from the C(sp(3))-H bond and Selectfluor acts to trap the resulting carbon radical to form the C(sp(3))-F bond. This simple metal-free protocol enables the chemoselective introduction of a fluorine atom into various aromatic and aliphatic compounds and serves as a powerful tool for the efficient synthesis of fluorinated molecules.

  Metal-Free Direct Oxidation of Aldehydes to Esters Using TCCA

  摘要：

  Aromatic and aliphatic aldehydes are simply converted into esters by an efficient oxidative esterification carried out under mild conditions. The aldehydes are converted in situ into their corresponding acyl chlorides, which are then reacted with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols and phenols. A variety of esters are obtained in high yields.

  Poly(3,4-dimethyl-5-vinylthiazolium) iodide was used as a polymer precatalyst in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and phenazine for the oxidative esterification of aldehydes with alcohols. Selective functionalization of OH groups was achieved in the presence of NH2 groups. The poly(thiazolium) iodide/DBU/phenazine system exhibited excellent catalytic activity and could be reused
