[Structure: see text] A copper-catalyzedamidation of allylic and benzylic C-H bonds with both primary and secondary sulfonamides is described. The reaction is applicable to the coupling of a diverse set of hydrocarbon species with aryl, heteroaryl, and alkyl sulfonamides and is tolerant of a variety of functional groups. Mechanistic insight has been gained through the isolation of a benzylic acetate

hydrogen bond patterns. The use of QTAIMC and Hirshfeld surface analysis allowed elucidating the influence of functional groups and molecular arrangement on the strength of inter- and intramolecular non-covalent interactions in crystals and overall packing efficiency. It was found that the bulky memantine fragment hinders the formation of C(4) hydrogen-bonded chains, leading to the formation of dimeric

Thermophysical characteristics of fusion processes (melting points and fusion enthalpies) of the substances were studied using the DSC method. Transfer processes from buffer to 1-octanol, from buffer to 1-hexane and 1-hexane to 1-octanol were analyzed. The impact of the molecules’ structural modification on sublimation, solubility and solvation/hydration processes in the solvents was studied. Correlation
including α-amino acids, diamines, diphosphines, bis-oxazolines, and diimines, support efficient copper-catalyzedamination of benzylic hydrocarbons by anhydrous chloramine-T. Catalysts derived from homochiral ligands, particularly chiral diimines, effect aminosulfonation with low to moderate enantioselectivity.
