EPIMERIZATION OF ENDO- AND EXO-BORNEOLS IN THE PRESENCE OF AMMONIA AND/OR HYDROGEN ON A FUSED IRON CATALYST
Epimerization of borneols was noted upon their reaction with ammonia and/or hydrogen on fused iron catalyst.Borneols are hydroaminated to give bornylamines with predominance of the endo isomer.

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
