Abstract

A simple electrochemical procedure for the N-acylation and N-alkylation of benzoxazol-2 (3H)-ones has been set up via electrolysis of an ionic liquid containing a benzoxazolone followed by addition of saturated or unsaturated anhydrides or alkyl halides. The electrochemically induced N-functionalization of benzoxazol-2 (3H)-ones works very well in all tested ionic liquids, avoiding the use of volatile organic solvents. The N-acyl and N- ...
