Conclusions
-
1.
The conversions of spiro[4,5]decane on 0.5% platinum-alumina, 0.5% palladium-alumina, and 10% cobalt-alumina catalysts at 450° and a hydrogen pressure of 30 atm have been investigated.
-
2.
Under these conditions the main reaction is the isomerization of the spirane to naphthalene. This takes place most readily on the platinum catalyst.
-
3.
Rupture of the five-membered ring of the spirodecane and all the C-C bonds also takes place with the formation of small amounts of gem-disubstituted cyclohexanes and alkylbenzenes.
