In this Quarter, the research was focused continually on the two general tasks: Task 1, molecular organometallic catalysts for hydrogenation and Task 2, organic base catalysts for arene hydrogenation and the hydrotreating of the coal liquids. With regards to Task 1, the mechanism of the hydrogenation of aromatic compounds catalyzed by [1,5-HDRhCl]{sub 2}/buffer system in the presence of small amount of surfactant under biphasic condition has been investigated. For the Task 2, potassium bis(trimethylsilyl)amide was applied for the hydrogenation of polycondensed aromatic hydrocarbons such as pyrene and anthracene. These polycondensed aromatic hydrocarbons can be hydrogenated in high yields to the corresponding monoaromatic hydrocarbons. Anthracene was hydrogenated to octahydroanthracene, a monoaromatic compound, in near 100% yield under 1000 psig of H{sub 2} and 250{degrees}C. A communications that described the very exciting use of H{sub 3}O{sup {minus}} for the hydrogenation of representative coal compounds was submitted to Energy and Fuels
