摘要：
Within DFT (B3LYP) methods the potential surface of the interaction between 1-iodopropan-2-one and 1,2,3-benzotriazole resulting in the formation of 1,3-bis(2-oxopropyl)-3H-1,2,3-benzotriazolium triiodide is studied. A mechanism consisting of four steps (N1-alkylation of 1,2,3-benzotriazole, elimination of molecular iodine during partial reduction of 1-iodopropan-2-one with hydrogen iodide, formation of the triiodide structure, and formation of 1,3-bis(2-oxopropyl)-3H-1,2,3-benzotriazolium) is proposed. Thermodynamic and kinetic parameters of these steps are obtained.
