Purification Methods
Purify the diene by dissolving it in Et2O, washing with 5% HCl, H2O, drying (MgSO4), evaporating, and the residue is distilled under dry N2 through a semi-micro column (some foaming occurs) [Cope et al. J Am Chem Soc 79 6287 1957, UV: Pesch & Friess J Am Chem Soc 72 5756 1950]. [Beilstein 5 IV 390.]
Check Digit Verification of cas no
The CAS Registry Mumber 4054-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4054-38:
(6*4)+(5*0)+(4*5)+(3*4)+(2*3)+(1*8)=70
70 % 10 = 0
So 4054-38-0 is a valid CAS Registry Number.

Photochemical Rearrangements of C6H8, C7H10, and C8H12 Radical Cations in Solid Argon at 20 K
Kelsall, Benuel J.,Andrews, Lester
, p. 2723 - 2729 (2007/10/02)
C6H8 radical cations have been produced by matrix photoionization techniques and trapped in solid argon.Electronic spectra show that two different types of products are formed; a conjugated diene cation with strong and weak absorption between 30000 and 20000 cm-1 and conjugated triene cations with a strong absorption between 28000 and 22000 cm-1 and weak absorptions between 18000 and 14000 cm-1.With selective photolysis in the high-energy bands, the conjugated triene cation geometric isomers were interconverted while the cyclic diene cations were ring opened to give conjugated triene cations.Similar experiments with cyclic and bicyclic C7H10 cations gave three conjugated heptatriene cation conformers, and cyclic C8H12 cations yielded a number of conjugated octatriene cation isomers.
Investigation of Rearrangement Reactions of Cyclic Allyl and Pentadienyl Anions
Sustmann, Reiner,Dern, Heinz-Juergen
, p. 2958 - 2971 (2007/10/02)
Bicyclohexenyl anion (1) and bicycloheptenyl anion (2) rearrange in THF to monocyclic pentadienyl anions, whereas bicyclooctenyl anion 3 is stable under the reaction conditions. 3 in contrary is formed by the known electrocyclic ring closure of cyclooctadienyl anion 7.Rearrangements of cyclopentenyl anion and pentadienyl anion are not detected.Cyclic allyl anions are alkylated by ethene, formed by cleavage of THF with base or independently added. 6,6-Dimethylcyclohexadienyl anion undergoes slow fragmentation to toluene at room temperature.
