Thermolabile Hydrocarbons, XXI. Relationships between Thermal Stability and Strain of Non-Symmetrical Highly Branched Hydrocarbons

The pyrolysis reaction of 20 hydrocarbons 3 into radicals 4 and tert-butyl radicals was investigated by product analysis and kinetics.It is shown that the same relationships between the free enthalpies of activation and the strain energies observed earlier for the cleavage of symmetrically substituted CC bonds are valid for the cleavage of unsymmetrical substituted bonds.The introduction of the new concept "strain energy of dissociation" (difference in strain between the ground state 3 and the residual strain in the radical fragments 4 and 5) has proven to be particularly useful.It is now possible to predict the rate of homolytic cleavage of almost all simple CC bonds by force field calculations.

Heterogeneous Catalysis, VI. Direct Reduction of Alcohols to Hydrocarbons

Secondary and tertiary alcohols are converted cleanly to the parent hydrocarbons in the gas phase with H2 in the presence of a Ni/Al2O3 catalyst at 190 deg C.Primary alcohols are dehydroxymethylated; e.g., 1-hydroxymethyladamantane (4) gives adamantane (1).Alumina alone, in the absence of Ni, results in the formation of homoadamantane (5) from 4. - Keywords: Gas Phase Hydrogenolysis, Homoadamantane Preparation
