The general catalytic synthesis of aryl and vinyl thioethers from readily available halides remains a challenge. Herein we report a unified method for the thiolation of aryl and vinyl iodides with dialkyl disulfides using visible light photoredox catalysis. A range of thioether products bearing diverse functional groups can be accessed in high yield and with excellent chemoselectivity. We demonstrate the versatility of this method through the expedient synthesis of a family of thioether-rich natural products. A detailed investigation of the photocatalytic mechanism is presented from both steady-state and time-resolved luminescent quenching as well as transient absorption spectroscopy experiments.

A wide range of air-stable, solid, polyfunctional aryl and heteroarylzinc pivalates were efficiently prepared by either magnesium insertion or Hal/Mg exchange followed by transmetalation with Zn(OPiv)2 (OPiv=pivalate). By reducing the amount of

Chemical Equation Presented A variety of thiomethyl-substituted N-heterocycles such as pyridines, isoquinolines, pyrimidines, pyrazines, pyridazines, quinazolines, triazines, benzothiazoles, or benzoxazoles undergo smooth Ni-catalyzed cross-coupling reactions with functionalized aryl-, heteroaryl-, alkyl-, and benzylic zinc reagents using an inexpensive Ni(acac)2/ DPE-Phos catalytic system at 25°C.
