Abstract Electrosynthesis of selenylated‐oxazolone derivatives via cascade selenylation/cyclization ynamides was disclosed. A series diaryl diselenides, dialkyl and heteroaryl‐substituted tolerated in this protocol delivered 4‐selenyloxazolones 28–83% yields. The scale‐up reaction the oxidation performed to showcase practicability method. Furthermore, mechanistic experiments indicated that a cationic pathway instead radical probably involved.

Abstract Herein, an efficient method for the synthesis of 5‐arylselenyluracils via bromide‐catalyzed selective C( sp 2 )‐H selenylation uracils using boronic acid and elemental selenium as selenyl source was successfully developed. This proceeded smoothly a series arylboronic acids under metal‐free strong oxidant‐free conditions. protocol offered simple catalytic conditions, high efficiency, good functional group compatibility, easy operation, scalable. Furthermore, mechanistic studies suggested that this transformation possibly undergone radical pathway.
