The first example of molecular sieve-promoted TBHP-mediated direct oxidative thiolation of an sp3 CâH bond adjacent to a nitrogen atom with disulfides under metal-free conditions, which allows for preparation of numerous S,N-containing compounds, is presented. Moreover, diverse benzothiazoles and a fipronil analog can be synthesized through this strategy.

分子筛促进的
TBHP介导的直接氧化
硫化反应,针对与氮原子相邻的sp3 C–H键进行的实验,该反应使用二
硫化物,使得制备大量含S、N的化合物成为可能。此外,还可以通过这一策略合成多种
