Scientific school prof. L.V. Kuritsyna at the Federal State Budgetary Educational Institution of Higher Education "Ivanovo State University" for several decades has been conducting comprehensive studies of the reactivity of amino compounds in N-acylation with derivatives of carboxylic and sulfonic acids. This monograph summarizes the results of the work of the team of authors on the study of kinetic laws and reaction mechanisms for the formation of amides and sulfonamides based on amino compounds of different classes: aliphatic, aromatic and mixed amines,? -aminoacids and dipeptides.
