2-Chloro-N-methylbenzothiazolium trifluoromethanesulphonate: an efficient condensing agent for the preparation of thiol esters and amides
Abstract
2-Chloro-N-methylbenzothiazolium trifluoromethanesulphonate is readily prepared and handled, and effects the formation of thiol esters and amides in excellent yields under mild non-acidic conditions.
