1,4-Etheno-1,4-dihydronaphthalene, also known as 1,4-Didehydro-1,4-dihydronaphthalene, is an organic compound with the chemical formula C10H10. It is a colorless liquid with a strong aromatic odor and is a derivative of naphthalene, a bicyclic aromatic hydrocarbon. 1,4-Etheno-1,4-dihydronaphthalene is characterized by the presence of a vinyl group (C=C) at the 1,4-positions of the naphthalene ring, which gives it unique chemical properties and reactivity. It is used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals and dyes. Due to its reactivity, it is typically handled under controlled conditions to prevent unwanted side reactions.

7322-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7322-47-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,2 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7322-47:
(6*7)+(5*3)+(4*2)+(3*2)+(2*4)+(1*7)=86
86 % 10 = 6
So 7322-47-6 is a valid CAS Registry Number.

Stepwise mechanisms in cyclopropylcarbene reactions

Cummins, Jordan M.,Porter, Timothy A.,Jones Jr., Maitland

, p. 6473 - 6476 (2007/10/03)

Decomposition of a naphtho-fused cyclopropyldiazomethane leads to benzocyclooctatetraene, 1-vinylnaphthalene, 2-vinylnaphthalene, and small amounts of benzobarrelene. Diradical intermediates are postulated.

Synthesis, Reactions and Thermal Properties of endo-5,12:endo-6,11-Dietheno-5,5a,6,11,11a,12-hexahydronaphthacene

Lin, Cheng-Tung,Wang, Nae-Jen,Yeh, Yu-Lin,Chou, Teh-Chang

, p. 2907 - 2928 (2007/10/02)

The title compound 6 was synthesized in nine steps, starting from the Diels-Alder adduct 21 of ketomethanoethanonaphthalene 20 and p-benzoquinone, via 7,8-dimethylidenediethenoanthracene 10 followed by Diels-Alder reaction with (E)-bis(phenylsulfonyl)ethylene and aromatization.Photocyclization of 6 led to 32 via an intramolecular cycloaddition.Hydrogenation and epoxidation of 6 gave the corresponding bis-benzo hydrocarbon 33 and bis-epoxide 34.Bromination of 6 proceeded by transannular reaction to produce N-type exo, endo dibromide 35b and U-type exo, exo dibromide 36b.Compound 6 underwent thermal decomposition at 210 +/- 5 deg C to form naphthalene and benzobarrelene.
