Bicyclo[2.1.1]hex-2-ene, also known as norbornene, is a cyclic olefin with the molecular formula C7H12. It is a colorless liquid with a strong, pungent odor and is widely used as a monomer in the production of various polymers, such as norbornene-based resins and copolymers. The bicyclic structure of norbornene consists of two carbon rings, with one being a six-membered ring and the other a three-membered ring, connected by a double bond. This unique structure provides norbornene with high thermal stability and resistance to degradation, making it an attractive candidate for various industrial applications, including the production of plastics, adhesives, and coatings. Additionally, norbornene is used as a building block in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.

822-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 822-41-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 822-41:
(5*8)+(4*2)+(3*2)+(2*4)+(1*1)=63
63 % 10 = 3
So 822-41-3 is a valid CAS Registry Number.

The Influence of Intramolecular Dynamics on Branching Ratios in Thermal Rearrangements

Newmann-Evans, Richard H.,Simon, Reyna J.,Carpenter, B. K.

, p. 695 - 711 (2007/10/02)

1- and 2-phenylbicyclohex-2-enes-5-d undergo thermal rearrangement to give products, differing only in the location of the deuterium, in ratio of about 9:1, but with identical activation enthalphies.Similarly, opticallly active trans-2-methyl-1-(trans-2-phenylethenyl)cyclopropane is found to rearrange to enantiomeric methylphenylcyclopentenes that are formed in a 5.9:1 ratio but with virtually identicyl activation enthalphies.Barring repeated coincidence, these results do not seem to be explicable within the framework of statistical theories of unimolecular kinetics such as RRKM theory, transition state theory, and variational transition state theory.The possible influence of dynamic effects in these and other unimolecular reactions is discussed.

Zur Photochemie des cis-1,3-Divinylcyclobutans

Trautmann, Walter,Musso, Hans

, p. 982 - 989 (2007/10/02)

The title compound 7 is obtained by ozonolysis of bicyclohex-2-ene (5) and Wittig reaction of the dialdehyde 6.There was no intramolecular photo-cycloaddition observed by irradiation of 7 but rearrangement to cis- and trans-allylvinylcyclopropanes 10 and 11.With the esters 12 - 14 the light energy is wasted in cis-trans-isomerisations.In comparison, the cis-1,3-cyclopentane derivatives 16 and 17 give some cycloaddition.
