Abstract
Download PDF Post

An ionic liquid promoted green and environment friendly synthesis of N-tosyl imines of aromatic aldehydes is described. The present
protocol involves use of ionic liquid without any added catalyst to afford the corresponding products in moderate to excellent yield (80-
95%). The process is easy for isolation, tolerance towards both electron-donating and electron-withdrawing substrates which makes it as a
valuable method in synthetic chemistry

Key words: p-toluenesulfonamide, tosylation, N-tosyl imines, ionic liquid.
