ABSTRACT:
An improved process is described for the homogeneous hydrogenation of polycyclic aromatic hydrocarbons utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the process to be conducted under mild conditions of temperature and pressure with high selectivity for the production of partially hydrogenated derivatives of polycyclic aromatic hydrocarbons such as 1,2,3,4-tetrahydronaphthalene, and eliminates the need for the presence of base or carbon monoxide atmosphere in the process.
