摘要

Density functional theory (DFT) calculations have been performed to investigate the oxidation of alcohol to acetaldehyde, catalyzed by the (bpy) Cu-I-TEMPO/NMI catalytic system. Three pathways (path A, path B and path C) are presented. Our calculations indicate that path B is the favourable pathway. In path B, the alcohol coordinating to the Cu-I center provides a H atom to TEMPO to form TEMPOH. Another TEMPO then replaces TEMPOH to abstract the H atom from the C-alpha-H of the alcoholate (RCH2O-) to generate the aldehyde product. On the basis of the studied pathway, a possible mechanism is presented to explain the experimental observations.
