Abstract

V. Z. Fridman and A. A. Davydov made a commentary on the "Dehydrogenation of Cyclohexanol on Copper Containing Catalysts--1. The Influence of the Oxidation State of Copper on the Activity of Copper Sites" published in the Journal of Catalysis 195, 20 (2000). Different from the mechanism depicted by the authors, no direct Cu-catalyzed formation of phenol occurred from cyclohexanol. Dehydrogenation to cyclohexanone intermediate and its conversion to phenol was the only process of phenol formation from cyclohexanol on metallic copper. Comparing the ratio of the phenol/cyclohexanone formation rates obtained by the authors for monometallic Cu with those obtained by them for Cu-MgO, Cu-ZnO, and Cu-ZnO/Al 2 O 3 excluded dismutation as a possible way of cyclohexanone-phenol conversion. Presumably, the surface π-complex of cyclohexanone intermediate was transformed into phenol via dehydrogenation of the six-member hydrocarbon cycle.
