A facile and efficient visible-light-driven method has been developed to construct sulfoxides via oxidative coupling of aryldiazo sulfones with thiols using the O₂ in air as the oxidant. This reaction could be performed at room temperature under catalyst- and additive-free conditions. The present methodology offers a mild and environmentally benign approach to obtain a library of sulfoxides in good yields with favorable functional group tolerance.

A mild and facile visible-light-mediated strategy has been proposed for the synthesis of 3-acyl quinoxalin-2(1H)-ones through acridine red catalyzed aerobic oxidative decarboxylative acylation of α-oxo-carboxylic acids with quinoxalin-2(1H)-ones at room temperature in air. Various 3-acyl quinoxalin-2(1H)-ones could be efficiently obtained in good yields with excellent functional group compatibility.

A novel visible-light-induced and Rose Bengal catalyzed strategy has been developed for the synthesis of α-ketoamides via decarboxylative acylations of isocyanides with α-oxocarboxylic acids and water under mild conditions.

A new and facile visible-light-enabled method for the synthesis of α-azidoketones has been developed via oxyazidation of alkenes with TMSN₃ in air at room temperature. A series of α-azidoketones could be easily and efficiently obtained in moderate to excellent yields via cascade C–N and CO bond formation by simply using low-toxic and inexpensive Rose Bengal (1 mol%) and PhSeSePh (5 mol%) as co-catalysts.
