In a previous study, some preliminary results showed that a particular cobalt stearate-aluminum alkyl (Co(stearate)/sub 2/Et/sub 3/Al) (I) homogeneous transition metal complex related to Ziegler catalysts was a very effective hydrogenation promoter under mild temperature conditions (50-100/degree/C) and hydrogen pressures of from 500-1000 psi. Since most of the aromatic structures studied consisted of one, two and three ring units, the Ziegler catalysts used as hydrogenation catalysts should successfully add hydrogen to the aromatic rings in coal. Significantly, aromatic compounds such as naphthalene (II) and polynuclear nitrogen heteroaromatic compounds such as quinoline (III) are found to occur in coal and oil shale. The selective hydrogenation of these materials to form additional useful compounds i.e., naphthalene (II) to form 1,2,3,4-tetrahydroanaphthalene (IV) would provide an alternate use of a rather abundant natural resource. Recently, it has been reported that quinolines and isoquinoline can be selectively hydrogenated in the nitrogen-containing ring to form 1,2,3,4-tetrahydroquinoline (V) and N-formyl-1,2,3,4-tetrahydroisoquinoline by means of a carbon monoxide and water mixture in the presence of a catalytic amount of rhodium carbonyl cluster at 150/degree/C, 800 psi hydrogen and with stirring for 24 hr. We wish to report that similar hydrogenation of naphthalene (II), quinoline (III), 2-methylquinoline, and isoquinoline can be carried out using catalysts (I) under somewhat milder conditions but no hydrogenation occurs for nitro- or chloro substituted quinolines. We will also discuss the results of using catalyst (I) to hydrogenate Illinois no. 6 coal from the premium coal sample program.
