A gold(I)-catalyzed oxidative diketonization of alkynes by water in the presence of Selectfluor has been achieved. The application of the present protocol for the one-pot synthesis of quinoxaline derivatives from alkynes and o-phenylenediamines has also been successful.

Herein, we have developed an electrochemical technique that enables the regioselective construction of 4-sulfenyl-1H-isochromen-1-ones in an undivided cell under external acid, catalyst, oxidant, or metal-free conditions.
