Description
An eco-friendly, straightforward and high-yielding methodology for the synthesis of chalcogenyl oxadiazoles via the K2CO3-promoted direct C-H bond chalcogenation of 2-substituted-1,3,4-oxadiazoles is described herein. The reaction was performed in the absence of metal catalyst and inert atmosphere using only half an equiv. of dichalcogenide and a low-cost base.
