The thermal decomposition of 1,2-dihydronaphthalene (DHN) at 300/sup 0/ produces tetralin, naphthalene, hydrogen, and five C/sub 20/ hydrocarbon products. The isolation of five C/sub 20/ hydrocarbon compounds revealed that two of the compounds are formed by the addition of 2-hydronaphthyl to DHN followed by intramolecular cyclization and hydrogen abstraction. A third compound was formed by the addition of the 1-tetralyl radical to DHN followed by hydrogen abstraction, and the other two compounds were formed by a sequence involving initial addition of 2-tetralyl radical to DHN. The thermal decomposition of DHN at 400-450/sup 0/C leads to the formation of a hydrogen atom which participates in subsequent hydrocracking reactions of available substituted aromatic structures.
