Abstract

Abstract High effectiveness of new condensing agents on the basis of complexes of silicon and phosphorus chlorides with nitrogen-containing bases in the synthesis of amides from carboxylic acids and amines and also in heterocyclization is shown. Factors affecting the readiness of formation of the amide bond and the yields of the final products are established.
