- ... An operationally simple, economical, and practical new method for the synthesis of highly functionalized 1,2-dithiols has been developed by copper catalyzed self-coupling of α-enolic dithioesters via consecutive formation of S–S and C–C bonds. Low-cost copper powder together with Ag2O as oxidant and promoter can be recycled at least four times with no loss of catalytic activity, making this strate ...
