An efficient and practical synthesis of 1,3-diyne-based sulfonamides using CuCl2/Et3N as a catalytic system is disclosed. Mild reaction conditions, atom-economy and high yields (50–91%) make this method an attractive option for the preparation of 1,3-diyne-based sulfonamide derivatives.

Due to the high oxidation potential between AuI and AuIII, gold redox catalysis requires at least stoichiometric amounts of a strong oxidant. We herein report the first example of an electrochemical approach in promoting gold-catalyzed oxidative coupling of terminal alkynes. Oxidation of AuI to AuIII was successfully achieved through anode oxidation, which enabled facile access to either symmetrical or unsymmetrical conjugated diynes through homo-coupling or cross-coupling. This report extends the reaction scope of this transformation to substrates that are not compatible with strong chemical oxidants and potentiates the versatility of gold redox chemistry through the utilization of electrochemical oxidative conditions.
