(Chemical Equation Presented). Thermal equilibrations among the three possible monodeuterium-labeled 1,3-cyclohexadienes have been followed in the gas phase at temperatures from 254 to 284°C. The temperature-dependent rate constants for the 1,5-shift of a

In homogeneous solution, partly in the presence of a phase-transfer catalyst, rhodium(III) chloride catalyzes the disproportionation of 1,3-cyclohexadiene and to a lesser extent 1,5-H shifts.In the start phase the catalyst is reduced to the active monovalent state.In these catalytic systems the dehydrogenation proceeds stereoselectively. - This was shown by tracer experiments and isotopes effects using deuterated 1,3-cyclohexadienes 1a-d, which were synthesized with high isotopomeric purity.Key Words: Rhodium chloride / Hydrogen transfer / Deuterated 1,3-cyclohexadienes / Isotope effects
