Cyclopent indene

Bromine-atom atomic resonance absorption spectrometry (ARAS) has been applied to measure the thermal decomposition rate constants of CF3Br in Kr over the temperature range 1222-1624 K. The results were found to be consistent with recently published theory. The formation of cyclopent[a]indene and acenaphthylene from alkyl esters of biphenyl-mono- and -di-carboxylic acids has been observed in flash vacuum pyrolyses at 1000-1100 °C. The kinetics and mechanisms of free-radical generation in the ternary system containing styrene epoxide, / -TsOH, and i-PrOH have been examined in both the presence and absence of O2. ...

Cyclopentadienyl ligands on transition metal complexes are usually spectators . There are, however, some titanium and cobalt complexes whose cyclop entadienyl ligands participate in C-C bond cleaving reactions. For example, the titanacycle 105 rearranged to 107 presumably through 106 (Scheme 7.42) [58]. Treatment of 107 with O2 induced further rearrangement to afford the indene 108 [59]. On the other hand, when treated with azobenzene at 60 °C, a mixture of 108 and 109 was formed [60]. This result indicates that the rearrangement between 106 and 107 is reversible.
