The inital rate (r0) of the hydrogen-transfer reaction from D-fenchol to menthone has been found to obey the following eqation r0,j = kjpA where k is the rate constant, pA is the partial pressure of D-fenchol, and the subscript j denotes any one of the optical isomers (L-, D- and D,L-) of menthone.The reaction is enantiomer-differentiating: kL > kD, and the optical resolution of D,L-menthone takes place in the reaction between D-fenchol and D,L-menthone.The experimental results are explained on the bases of an Eley-Rideal-type mechanism and stereochemically consistent transition-state models.Probable adsorption models for menthone are also proposed.
