  • Thiyl radical promoted iron-catalyzed-selective oxidation of benzylic sp<sup>3</sup> C–H bonds with molecular oxygen
    作者:Shasha Geng、Baojian Xiong、Yun Zhang、Juan Zhang、Yun He、Zhang Feng
    DOI:10.1039/c9cc06584a
    日期:——
    A ligand-free iron-catalyzed method for the oxygenation of benzylic sp3 C–H bonds by molecular oxygen (1 atm) using a thiyl radical as a cocatalyst has been developed. This transformation provides a facile access to amides, esters and ketones from readily accessible corresponding amines, ethers and alkanes. It features high regioselectivity, mild oxidative conditions and excellent functional group
