ABSTRACT:
Cyclic polyenes are selectively hydrogenated to cyclic monoenes under suitable hydrogenation conditions in the presence of an activated ruthenium catalyst complexes. The ruthenium catalyst complex is activated by hydrogenating a minimal amount of cyclic polyene under suitable hydrogenation conditions.
