Palladium-Catalyzed Coupling of Azoles or Thiazoles with Aryl Thioethers via C–H/C–S Activation
摘要:
Palladium-catalyzed cross-coupling via the (CspS)-S-2 bond activation of aryl thioethers and the C-H bond activation of azoles or thiazoles was carried out. Electron-deficient and -rich aryl methyl thioethers and diaryl thioethers can be employed as the coupling partners and the reaction tolerates a range of functional groups including MeO, CF3, CN, PhCO, CONEt2, and Py groups.

A nickel-catalyzedheteroareneC−H/arenol C−OH coupling reaction is reported, which omits the use of strong Lewis-acid additive and low atom-economy protecting reagent. Arrays of arenols and heteroarenes are effective in this protocol using the in-situ activating reagent pivalic anhydride.
