1-Oxaspiro[2.5]octane, 6-(1,1-dimethylethyl)-, trans- is a complex organic chemical compound with the molecular formula C11H20O. It is a cyclic molecule with a spiro structure, consisting of a six-membered ring fused to a five-membered ring, with an oxygen atom bridging the two rings. The compound features a trans-configuration, indicating that the substituents on the double bond are positioned on opposite sides of the molecule. The 6-position of the molecule is occupied by a 1,1-dimethylethyl (tert-butyl) group, which is a bulky, sterically hindered group that can influence the compound's reactivity and physical properties. This specific arrangement of atoms and functional groups gives the compound unique chemical and physical characteristics, making it potentially useful in various applications, such as pharmaceuticals or materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 18881-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,8 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18881-26:
(7*1)+(6*8)+(5*8)+(4*8)+(3*1)+(2*2)+(1*6)=140
140 % 10 = 0
So 18881-26-0 is a valid CAS Registry Number.

Carbodiimide-Promoted Olefin Epoxidation with Aqueous Hydrogen Peroxide

Majetich, George,Hicks, Rodgers,Sun, Guang-Ri,McGill, Patrick

, p. 2564 - 2573 (2007/10/03)

Commercially available carbodiimides in hydroxylic solvents containing hydrogen peroxide with mildly basic or acidic catalysts have been found to promote the epoxidation of olefins. A commercially available 30% aqueous solution of hydrogen peroxide serves as the oxidant for this process. The presumed reactive species is a peroxyisourea generated in situ by the addition of hydrogen peroxide to the carbodiimide.

EPOXYDATION EN MILIEU HETEROGENE SOLIDE-LIQUIDE: EFFET DES INTERACTIONS A L'INTERFACE SUR LA STABILITE DE L'YLURE DE DIMETHYLSULFONIUM - CONSEQUENCES SUR LA STEREOCHIMIE DE LA REACTION D'EPOXYDATION

Borredon, Elisabeth,Delmas, Michel,Gaset, Antoine

, p. 1877 - 1880 (2007/10/02)

The use of solid-liquid heterogenous system in a low hydrated organic medium during the epoxidation reaction of rigid cyclohexanones stabilizes the dimethylsulfonium ylide.The stereochemistry of the reaction is then modified and results to be different from the one obtained in an anhydrous homogeneous medium.However the ylide stability is not sufficient to lead to a cyclopropyl by-product with the α-ionone.
