THE HYDROGENATION OF cis- AND trans-1,3-PENTADIENE IN THE PRESENCE OF (η5-C5H5)NiOs3(μ-H)3(CO)9. A NEW METHOD TO CARRY OUT HOMOGENEOUS OR HETEROGENEOUS CATALYSIS AND THE ANALYSIS OF THE PRODUCTS IN A GAS-CHROMATOGRAPHIC APPARATUS

The title complex, a very stable cluster, is active in the hydrogentaion of alkynes, alkenes and pentadienes in homogeneous conditions.When supported onto Chromosorb P, the complex hydrogenates the pentadienes with high efficiency.There is evidence for operation of both homogeneous or heterogeneous processes, the relative contributions depending on the temperature and the ageing of the system.With a flow of hydrogen, coupling of the hydrogenating vessel with an analytical column forms a versatile catalytic-analytical system which may be operated from room temperature to about 150 deg C.
