摘要

A multifunction Pd/Sc(OTf)(3)/ionic liquid catalyst for the tandem one-pot conversion of phenol to e-caprolactam is reported. Pd and Sc(OTf)(3) cooperate to catalyze the hydrogenation of phenol to cyclohexanone with excellent conversion (%26gt;99.9%) and selectivity (%26gt;99.9%), whereas Sc(OTf)(3) and an ionic liquid, [bmim] [PF6], cooperate to catalyze the tandem transformation of the resulting cyclohexanone to cyclohexanone oxime and the Beckmann rearrangement affording epsilon-caprolactam.
