2103063 9220639 PCTABS00017 A process and catalyst for isomerizing olefins are disclosed. The process and catalyst are particularly useful for isomerizing alkenyl bridged ring compounds to the corresponding alkyladiene bridged ring compounds. The isomerization catalyst comprises an oxygen treated mixture of an alkali metal on a calcined support having a surface area of 125 to 195 m2/g. The catalyst is particularly useful for isomerizing 5-vinyl-2-norbornene to 5-ethylidiene-2-norbornene. The catalyst is very active and highly selective and resistant to catalyst poisons. The process contacts the catalyst with an alkenyl bridged ring compound and yields the corresponding alkyladiene bridged ring compound.
