Generation of benzocyclohex-1-en-3-yne in two ways leads to naphthalene and methyleneindene (benzofulvene). Labeling studies favor a multistep mechanism involving an initial electrocyclicringopening, and carbene−alkene interconversions.

The thermal isomerization of azulene was studied behind reflected shocks in a pressurized driver single-pulseshocktube. The temperature range covered was 1050–1400 K at overall densities of ∼2.5 × 10−5 mol/cm3. The main reaction of azulene under these conditions is a unimolecular isomerization to naphthalene, but it also isomerizes, although at a much lower rate, to another isomer. The suggested
在加压驱动器单脉冲激波管中,在反射激波后面研究了氮杂的热异构化。所覆盖的温度范围为1050–1400 K,总密度约为2.5×10 -5 mol / cm 3。在这些条件下,z烯的主要反应是单分子异构化为萘,但是它也异构化为另一异构体,尽管速率低得多。氮杂-萘异构化所建议的“四环三烯”中间结构还可导致过渡态,该过渡态可描述异构化为1-亚甲基-1H-茚和1,2,3-二甲基-1H-茚,2,3-二氢。少量的C 2 H 2,C 4 H 2,C 6 H在震后样品中也发现了6和C 6 H 5- C≡CH,特别是在高温下。异构化过程的两个高压极限速率常数的Arrhenius参数为:
Aromatic hydrocarbon growth from indene

Aromatic hydrocarbon growth from indene (C9H8), which contains the five-membered ring cyclopentadienyl moiety, was investigated experimentally in a 4 s flow reactor over a temperature range 650-850 degrees C. Major products observed were three C18H12 isomers (chrysene, benz[a]anthracene and benzo[c]phenanthrene), two C17H12 isomers (benzo[a]fluorene and benzo[b]fluorene), and two C10H8 isomers (naphthalene
