Quenched skeletal Ni as the effective catalyst for selective partial hydrogenation of polycyclic aromatic hydrocarbons

Quenched skeletal Ni is an active and selective catalyst for selective partial hydrogenation of polycyclic aromatic hydrocarbons (PAHs). The molecular structure of PAHs significantly dominate the hydrogenation process and furthermore, the distribution of hydrogenated products.

Hydrogenation of pyrene using Pd catalysts supported on tungstated metal oxides

A series of Pd catalyst supported on tungstated metal oxides (Pd/W-MOx) were prepared and applied for pyrene hydrogenation, and the role of acid sites of supports was investigated. Among Pd/W-MOx catalysts, Pd/W-TiO2 showed the highest activity which was comparable to those of Pd/BEA, Pd/Y and Pd/SiO2-Al2O3. As for the Pd catalysts supported on metal oxides without tungstate (Pd/MOx), the hydrogenation activity became higher with the increase in the acid amount of supports measured by calorimetric measurement of ammonia adsorption. The important role of acid sites on hydrogenation activity was demonstrated. On the other hand, the hydrogenation activity of Pd/W-MOx catalysts was not correlated to the acid amount of supports measured by ammonia adsorption. On-site generation of protonic acid on tungstated metal oxide supports was estimated from kinetic analysis of reduced W species in the presence of hydrogen by in situ UV-visible measurement. From a good correlation between the kinetic parameters of on-site protonic acid formation and the hydrogenation activity, the important role of protonic acid formation on tungstated metal oxide supports was clarified.

Formation of sec-Alkylpyrenes by Friedel-Crafts and Cathodic Alkylation Methods. Structure and Spectroscopic Properties of Products. Catalytic Hydrogenation of Pyrene and Some Alkylpyrenes

Friedel-Crafts isopropylation of pyrene in neat isopropyl chloride yielded a series of mono, di, tri, tetra, and pentaisopropylpyrenes.Tetra and pentacyclopentyl- and cyclohexylpyrenes were formed analogously.Cathodic isopropylation by controlled potential electrolysis yielded both fully aromatic and partly hydrogenated isopropylpyrenes.Structure of these compounds, spectroscopic properties and mechanistic aspects of their formation are discussed.The catalytic hydrogenation (Raney nickel) of pyrene and isopropylpyrenes under very mild conditions has also been studied.
