24569-89-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24569-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,6 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24569-89:
(7*2)+(6*4)+(5*5)+(4*6)+(3*9)+(2*8)+(1*9)=139
139 % 10 = 9
So 24569-89-9 is a valid CAS Registry Number.

Formation of alternating copolymers via spontaneous copolymerization of 1,3-dehydroadamantane with electron-deficient vinyl monomers

Matsuoka, Shin-Ichi,Ogiwara, Naoto,Ishizone, Takashi

, p. 8708 - 8709 (2006)

Copolymerizations of 1,3-dehydroadamantane, 1, and various vinyl monomers were carried out in THF at room temperature. On mixing 1 with electron-deficient vinyl monomers, such as acrylonitrile and methyl acrylate, in the absence of any initiator, the copolymerization spontaneously proceeded to give alternating copolymers in 28-88% yield. By contrast, no reaction of 1 occurred at all when isobutyl vinyl ether or styrene was mixed under similar conditions. These contrastive results indicate the high electron density of a central σ-bond in a strained [3.3.1]propellane derivative, 1. Alternating sequences of the resulting copolymers were characterized by NMR and MALDI-TOF-MS measurements. DSC and TGA measurements revealed the high thermal stability of the alternating copolymers containing bulky, stiff, and strain-free adamantane skeletons. Copyright

Synthesis of poly(1,3-adamantane)s by cationic ring-opening polymerization of 1,3-dehydroadamantanes

Ishizone, Takashi,Matsuoka, Shin-Ichi,Sakai, Shiko,Harada, Wataru,Tajima, Hiroyuki

, p. 7069 - 7071 (2004)

Poly(1,3-adamantane)s was synthesized by cationic ring-opening polymerization of 1,3-dehydroadamantane. The all-hydrocarbon poly(propellane), poly(5-butyl-1,3-adamantane) synthesized showed good solubility and thermal stability. This high thermal stability of aliphatic polymers was derived from the strain-free adamantane skeletons and the stable carbon-carbon bond between two bulky adamantane rings. The chemical structure of the resulting polymer was characterized by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy in conjugation with infrared measurement and elemental analysis.

Catalytic reaction of halogenoadamantanes

Son, V.V.,Son, T.V.

, p. 2081 - 2083 (2007/10/02)

1,1'-Biadamantyl, 1,3-dehydroadamantane, and 3-methylenebicyclonon-6-ene were obtained by the catalytic reaction of 1-halogeno-, 1,3-dihalogeno, and cis-1,4-dibromoadamantane respectively with lithium in the presence of methyldiphenylchlorosilane.The methyldiphenylchlorosilane acts as a supplier of active lithium in the form of methyldiphenylsilyllithium.
