A new method for the preparation of alkyl aryl sulfides through direct oxidative thiolation of alkanes or ethers with arylsulfonylhydrazides using di-tert-butyl peroxide (DTBP) as an oxidant catalyzed by Pd(OAc)2 has been reported. The C-H bonds in various alkanes or ethers were successfully converted into C-S bonds to yield the corresponding sulfides in moderate to good yields.
A visible-light-promoted direct thiolation of α-C(sp3)–H in ethers with thiosulfonates was developed for the preparation of α-arylthioethers using easily availably Na2-eosin Y and TBHP as a photocatalyst and oxidant. This reaction occurred smoothly under the irradiation of 5 W blue light at room temperature and generated the corresponding products in good to excellent yields.
使用容易获得的 Na 2 -伊红 Y 和 TBHP 作为光催化剂和氧化剂,开发了可见光促进的 α-C(sp 3 )–H 在醚中与硫代磺酸盐的直接硫醇化,用于制备 α-芳基硫醚。该反应在室温下5W蓝光照射下顺利进行,并以优良的收率生成相应的产物。
