| Abstract |
2-Phenyl-5-(phenylethynyl)tetrazole 44 provides a new entry to the C15H10 energy surface. Flash vacuum pyrolysis of 44 using the falling solid flash vacuum pyrolysis (FS-FVP) method afforded cyclopenta[def]phenanthrene 31 and cyclopenta[fg]fluorene 52 as the principal products. The products are explained in terms of formation of N-phenyl-C-phenylethynylnitrile imine/(phenylazo)(phenylethynyl)carbene 45 and its cyclization to 3-(phenylethynyl)-3H-indazole 46b. Pyrolytic loss of N2 from 46b generates the C15H10 intermediate 48. Cyclization of 48 to a dibenzocycloheptatetraene derivative and further rearrangements with analogies in the chemistry of phenylcarbene and the naphthylcarbenes lead to the final products. Similar pyrolysis of 2-phenyl-5-styryltetrazole 43 afforded 3-styrylindazole 58, which on further pyrolysis eliminated N2 to generate 3- and 2-phenylindenes 61 and 62 via C15H12 intermediates. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 June 2015.
All research outputs
#20,657,128
of 25,377,790 outputs
Outputs from Journal of Organic Chemistry
#26,833
of 28,613 outputs
Outputs of similar age
#203,181
of 278,181 outputs
Outputs of similar age from Journal of Organic Chemistry
#72
of 95 outputs
Altmetric has tracked 25,377,790 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 28,613 research outputs from this source. They receive a mean Attention Score of 4.5. This one is in the 2nd percentile – i.e., 2% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 278,181 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 95 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
