Benzocycloheptatriene, also known as tropylium, is a cyclic aromatic compound with the molecular formula C7H7. It consists of a seven-membered ring with a benzene ring fused to it, containing seven carbon atoms and seven hydrogen atoms. This molecule is known for its unique structure, which is a result of the fusion of a benzene ring with a cycloheptatriene ring. Benzocycloheptatriene is an unstable compound and is often used as an intermediate in organic synthesis. It is also of interest to chemists due to its potential applications in the development of new materials and its role in understanding the electronic structure of aromatic compounds.

264-09-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 264-09-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 264-09:
(5*2)+(4*6)+(3*4)+(2*0)+(1*9)=55
55 % 10 = 5
So 264-09-5 is a valid CAS Registry Number.

Pyrolyse de dithiocarbonates aromatiques et du pentaerythrol

Kryczka, Boguslaw,Descotes, Gerard

, p. 475 - 482 (2007/10/02)

The thermolysis of dithiocarbonates derived from hydroxyphenols, aromatic glycols or pentaerythrol leads to elimination reactions, rearrangement or heterocyclization reactions according to their structures.

Stereochemistry of the Bicyclopentane Ringopening; Thermolysis of Tricyclo2,4>heptane Derivatives

Roth, Wolfgang R.,Klaerner, Frank-Gerit,Grimme, Wolfram,Koeser, Hans G.,Busch, Ralf,et al.

, p. 2717 - 2737 (2007/10/02)

Thermolysis of the anti-tricyclic compounds 6, 22 and 34 proceeds preferentially by concerted 2s+?2a>-reactions and leads to cis,trans-olefines 8, 24 and 37.The rearrangement of the syn-isomers on the other hand seems to be a nonconcerted reaction yielding the diradicals 15, 27 and 36.
