N-(p-Toluenesulfonyl)-1-(4′-acetylphenoxy)acrylimidate: Synthesis, Crystal Structure and Theoretical Studies

The formation of N-sulfonyl-1-aryloxy acrylimidate is described, for the first time, from a consecutive process, which involves a CuAAC reaction, a ketenimine formation and subsequent rearrangement between an aryl propargyl ether and a sulfonyl azide. The structure of this newly synthesized compound...

Summary:The formation of N-sulfonyl-1-aryloxy acrylimidate is described, for the first time, from a consecutive process, which involves a CuAAC reaction, a ketenimine formation and subsequent rearrangement between an aryl propargyl ether and a sulfonyl azide. The structure of this newly synthesized compound was analyzed by NMR spectra and unambiguously established by X-ray analysis. In addition, theoretical calculations, which included a Hirshfeld surface, FMO, QTAIM and NCI indices analysis, corroborated the formation of π-π stacking interactions among aromatic rings, as well as C-H···O interactions between vinyl hydrogens with ketone carbonyl oxygen.
