Abstract
Adamantane cpds. (I) are made by contacting fully hydrogenated >=12C aromatic 3-ring cpds. (II) with an Al halide catalyst in the presence of a hydrogen source. Method reduces formation of alkene by-products which deactivate the catalyst. Pref. (II) have >=16C, such as fully hydrogenated terphenyl, fully hydrogenated 2-phenylnaphthalene, etc. The isomerisation catalysts are prepf. complexes made by reacting an Al halide with a hydrogen halide and an >=7C satd. aliphatic hydrocarbon. The H2 source may be e.g. free H2 at a partial pressure of 1.75-35 kg/cm2, a 6-7C naphthene such as (di)methylcyclopentane, cyclohexane, or (I) itself with >=15C. Reaction is at -5 to +50 degrees C.
