Na=naphthalene, Ac = acenaphthylene, E=fluorene, Pa=phenan-threne, A = anthracene, El = fluoranthene, P = pyrene, BcE = benzo[c]fluoranthene, CPP = cyclopenta[c,4] pyrene, BaA = benz[a]anthracene, Ch = chrysene, 5-MeCh = 5 methylchrysene, BeP = benzo[e]pyrene, BjE = benzo[/ ]fluoranthene, BbF = benzo[h]fluoranthene, BkE = benzo[l ]fluoranthene, BaP = benzo[a]pyrene, DBahA = dibenz[a,/j]anthracene, DBalP = dibenzo[a,l]pyrene, BghiP = benzo[g,/j,i]perylene, IP = indeno [l,2,3-c4]pyrene, DBaeP = dibenzo[a,e]pyrene, BbCh = benzo[h]chrisene, DBaiP = dibenzo[a,i]pyrene,... 

It has been reported that 1 //-bcnz / indene (1), l//-benz[e]indene (2), l//-benz[/g] acenaphthylene (3), and 1 //-cyclopenta[/]-phcnanthrene (4), possessing planar carbon frameworks with a single secondary C(.sy 3)H2 centre, exhibit modest acidity in the gas-phase and in DMSO.1 The origin of their amplified acidity compared with cyclopentane, cyclopentene, and cyclopentadiene is the more pronounced anionic resonance, which distributes the negative charge over the whole planar carbon skeleton via mobile n-electrons. 

Fifty-four PAHs have been identified at one or more NPL hazardous waste sites. These 54 are acenaphthene, acenaphthylene, 2-acetoaminofluorene, anthracene, 9,10-anthracenedione, benz[a]anthracene, benzo[a]pyrene, benzo[e]pyrene, benzo[a]fluoranthene, benzo[b]fluoranthene, benzo[b]fluorene, benzofluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene. benzo[g,h,i]fluoranthene, benzoperylene, benzo[g,h,i]perylene, benzophenanthrene, benzopyrene, benzothiophene, benzo[b]thiophene, chrysene, 4H-cyclopenta[d,e,f]phenanthrene, dibenz[a,j]anthracene, dibenz[a,h]anthracene, 7,12- dimethylbenz[a]anthracene,...

Moreover, Tsuge and coworkers reported the reaction of 315 with 1-(1-pyrrolidinyl)acenaphthylene 352 which furnishes tetrahydroindeno[l, 2 ] cyclopenta[4,5- ]acenaphthelenes 353 and 354 in 57% and 30% yield, respectively. The reaction mechanism of the formation of 353 and 354 was proposed to proceed by a regioselective Cope rearrangement of the initially formed [2-1-2]cycloadduct 355, which subsequently isomerizes by a 1,3-hydrogen shift of 356 (Scheme 7.78) [89].
