|Section2= |Section7= }} Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. It is a colourless solid. Coal tar consists of about 0.3% of this compound.〔 ==Production and reactions== Acenaphthene was prepared the first time from coal tar by Marcellin Berthelot. Later Berthelot and Bardy synthesized the compound by cyclization of α-ethylnaphthalene. Industrially, it is still obtained from coal tar together with its derivative acenaphthylene (and many other compounds). Like other arenes, acenaphthene forms complexes with low valent metal centers. One example is (η6-acenaphthene)Mn(CO)3]+.〔S. B. Kim, S. Lotz, S. Sun, Y. K. Chung, R. D. Pike, D. A. Sweigart "Manganese Tricarbonyl Transfer (MTT) Agents" Inorganic Syntheses, 2010, Vol. 35, 109–128, . 〕 Chemical reduction affords the radical anion sodium acenaphthylenide, which is used as a strong reductant (E = -1.75 V vs NHE).〔N.
