Molecule-induced homolysis (MIH), the process by which two closed-shell molecules react to produce free radicals, has been recognized as an important contributing pathway to radical initiation during coal dissolution. The production of organic radicals by MIH and other pathways can lead in stepwise fashion to the production of highly reactive radicals to a significant degree at temperatures >400/sup 0/C. This paper summarizes results which show that the decomposition of 2,2-dihydronaphthalene (DHN) involves both 1-hydronaphthyl (1HN) and 2-hydronaphthyl (2HN) radicals as well as 1-tetralyl radical and that the production of 1HN and 2HN leads to the scission of hydrogen atom and its participation in subsequent hydrocracking reactions.
