A metal-and oxidant-free electrochemical method for preparing selenomethyl-substituted cyclic ethers or lactones via difunctionalization of olefines is presented. A series of selenomethylsubstituted cyclic ethers, particularly 9-and 11membered, selenomethyl-substituted lactones (4-6 membered), and selenomethyl-substituted phthalides can be obtained via this reaction. This method features convenient operation, an electron as oxidant, and ammonium iodide as electrolyte, thereby making it a green synthesis method.

Owing to the inert nature of the pyridine ring and high activity of iminyl radical, the reaction between pyridine and iminyl radical remains a significant challenge. In this paper, we...

A electrochemical method for the synthesis of 3,5-disubstituted-1,2,4-thiadiazoles through NH 4 I-mediated dimerization of thioamides is reported. Using the inexpensive NH 4 I as electrolyte and catalyst, this electrosynthesis approach requires no oxidizing agents and enables the convenient production of diverse 1,2,4-thiadiazoles products. The approach is an example of SÀN bond construction through the electrochemical method.

Methanol plays a crucial role in organic synthesis as a green C1 source. Herein, the concise α-methoxymeth- ylation and aminomethylation of propiophenones is achieved via electrochemistry with methanol as both...
