Despite the widespread use of transition-metal catalysts in organic synthesis, transition-metal-catalyzed reactions of organosulfur compounds, which are known as catalyst poisons, have been difficult. In particular, the transition-metal-catalyzed addition of organosulfur compounds to unactivated alkenes remains a challenge. A novel gold-catalyzed hydrothiolation of unactivated alkenes is presented, which

The thiol‐ene coupling (TEC) reaction has attracted a lot of scientific attention during the last years, particularly in the fields of polymers, materials and more recently in drug design. The combination of organocatalysis and photocatalysis has enabled the development of an efficient synergistic protocol for the addition of various thiols to a plethora of olefins. Utilizing phenylglyoxylic acid as
Scandium(III) triflate promoted highly selective addition of thiols to functionalizedolefins under mild conditions. The addition follows anti-Markovnikov regioselectivities, which are unusual for Lewis acids-catalyzed hydrothiolation. This reaction marks broad functional groups tolerance, which opens a beneficial synthetic route to functionalized and biologically active thio-compounds. This method

ortho-Alkynylbenzoic acid alkyl esters act as alkylating agents of thiol derivatives with PPh3AuCl in combination with AgOTf in 1,2-dichloroethane at 80 °C. The corresponding sulfide compounds are obtained in good to excellent yields.
