arylazo sulfones were used as radical precursors for carbon‐heteroatom bond formation under electrochemical conditions. Moreover, the scalability of this approach was evaluated by performing the electrochemical thiolation and borylation of arylazo sulfones with thiols and B2pin2 on a gram scale. This protocol not only avoided the use of stoichiometric oxidants, metal catalysts, activating agents and
Room‐temperaturephosphorescence (RTP)‐based sensors have distinctive advantages over the fluorescence counterparts, such as larger Stokes shifts and longer lifetimes. Unfortunately, almost all RTP sensors are operated on quenching‐based mechanisms given the sensitive nature of the emissive triplet state. Here we report a type of thioether RTP molecules that shows RTP “turn‐on” when volatile acid vapors
Copper chloride-catalyzed S-arylation of arenethiols is effected with activated aryl chlorides in neat water by using ethylenediamine as the pair ligand/base. This convenient, environmentally more friendly procedure for the coupling of aryl chlorides allows the arylation between sterically demanding coupling partners.
