An electrochemical selenylation/cyclization of N-allylthioamides has been developed for the synthesis of selenium-containing 2-thiazolines. This protocol provides an efficient approach to produce 2-thiazolines with broad substrate scope under mild reaction conditions. Preliminary mechanistic study indicates that selenium radical may be involved. The reaction is easy operated under catalyst- and oxidant-free conditions.

Key words: electrosynthesis, thiazolines, thioamides, selenation
