Abstract

A multifunction Pd/Sc(OTf)₃/ionic liquid catalyst for the tandem one-pot conversion of phenol to ε-caprolactam is reported. Pd and Sc(OTf)₃ cooperate to catalyze the hydrogenation of phenol to cyclohexanone with excellent conversion (>99.9%) and selectivity (>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 ε-caprolactam.
