摘要

class="kwd-title">Keywords: Density functional theory (DFT), Decomposition reaction, Charge decomposition analysis (CDA), Bonding analysis class="head no_bottom_margin" id="ab015title">AbstractThe reactions of Ni+ with propionaldehyde in the gas phase have been systematically investigated using density functional theory at the B3LYP/def2-TZVP level. The decomposition reaction mechanism has been identified. Our calculations indicated that Ni+ can assist decomposition of propionaldehyde to form Ni+CO and C2H6 through two types of reaction channel: C—C bond activation and C—H bond activation. In addition, charge decomposition analysis (CDA) was carried out to obtain a deeper understanding for orbital interaction of the initial complex. The bonding properties of the species involved were discussed by means of diverse analysis methods including electron localization function (ELF) and atoms in molecules (AIM).
