The reaction of the two different substitue carbonyl oximes (isonitrosoacetylnaphthaline, inanH and nitro-isonitrosoacetophenone, ninapH) with two different amines (1-phenylethanol amine, pea, and ethanol amine, ea) was carried out and characterized by elemental analyses, IR, and H-1 and C-13 NMR spectroscopic methods. As a result of these experimental studies, two different levels for all reactions were determined: (I) formation of imine oxime and (II) rearrangement of imine oxime or formation of amido alcohol. After a mechanism was suggested for all of these reactions, the reaction mechanism of carbonyl oxime with amine was first studied by means of the B3LYP/6-311G(d,p) method. Because of the deficiency of density functional theory (DFT) on dispersion effects, the wB97X-D/6-311G(d,p) method, which includes dispersion correction, was used to obtain the reaction heat and free energy barriers to explain why the formation (imine oxime) and unexpected rearrangement products (amido alcohol) occurred or did not occur. The statistical thermodynamic method was used to obtain the changes in thermodynamic properties of the studied molecules between 100 and 500 K. From a kinetic viewpoint, the slowest step of the reactions is the IN1-TS2-IN2 step, which determines the steps of the reaction kinetics. In addition, spectroscopic properties such as vibrational and NMR chemical shifts were studied for all of the molecules. The frontier molecular orbitals (FMOs), highest occupied molecular orbitals (HOMOs), and lowest unoccupied molecular orbitals (LUMOs) were monitored for all of the molecules.
