General Description

2,2'-Biadamantane is a synthetic organic compound with a unique molecular structure consisting of two adamantane units linked together by a carbon-carbon single bond. It is a highly stable and rigid molecule due to the bulky and symmetrical adamantane groups, making it useful for various applications in materials science and pharmaceutical research. 2,2'-Biadamantane has been studied for its potential as a building block for functional organic materials and as a core scaffold for drug development, with promising results in enhancing the thermal and chemical stability of polymers and as a potential pharmacophore for novel drug candidates. Additionally, its highly branched structure makes it an attractive candidate for the design of molecular machines and supramolecular assemblies. Overall, the unique properties of 2,2'-Biadamantane make it a versatile and valuable chemical for a wide range of scientific and industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 29542-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,4 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29542-62:
(7*2)+(6*9)+(5*5)+(4*4)+(3*2)+(2*6)+(1*2)=129
129 % 10 = 9
So 29542-62-9 is a valid CAS Registry Number.

Thermolysis of Highly Congested Tri-tert-alkylmethanes. Rearrangement of a 3-Noradamantylmethyl Radical

Lomas, John S.

, p. 519 - 528 (2007/10/02)

Activation energies for C-Ad fission in the thermolysis of di-1-adamantyl-tert-alkylmethanes and 1-adamantyl-di-1-bicyclooctylmethane, AdR1R2CH, in toluene are best correlated with the strain energy difference (MMP2 force field) between the methane and the corresponding radical, R1R2C radical H; difficulties were encountered in the application of MM3 to certain of these trialkylmethanes.Normally, the major thermolysis product is the di-tert-alkylmethane, R1R2CH2, but when a 3-noradamantly group is present (1d) the initially formed radical ring opens to give 1,2'-biadamantyl in amounts which depend on the temperature and the solvent (normal or octadeuteriated).This rearrangement is readily explained by MMP2 calculations.Since the cross-product yield is low (less than 3percent, even in deuteriated solvent at the highest temperature) the thermodynamic parameters for the hydrogen transfer and ring opening reactions of the 1-adamantyl-3-noradamantylmethyl radical can be compared directly.Both the activation enthalpy and entropy are much greater for ring opening than for hydrogen abstraction from the solvent.Isotope effects on hydrogen abstraction are high and satisfy certain criteria for tunnelling, as do data on the analogous reaction of Ad2C radical H.A more sophisticated treatment of the product composition for 1d thermolysis, using kinetic simulation, leads to essentially the same conclusions as the simpler treatment.

High-Yield Direct Synthesis of a New Class of Tertiary Organolithium Derivatives of Polycyclic Hydrocarbons

Molle, G.,Bauer, P.,Dubois, J. E.

, p. 2975 - 2981 (2007/10/02)

For the first time, 1- and 2-adamantyllithium, 1-diamantyllithium, 3,5,7-trimethyl-1-adamantyllithium, 1-twistyllithium, 3-methyl-7-noradamantyllithium, 1-triptycyllithium, and 3-homoadamantyllithium have been directly synthesized from the reaction of an organic halide and lithium metal.By use of certain experimental parameters, the phenomena at the metal-solution interface are controlled, thereby resulting in exceptionally high yields of this new class of organometallic compounds (>75percent, except in the case of 3-homoadamantyllithium).Competition between formation of the organometallic compound and formation of solvent-attack byproducts is determined by the degree of adsorption of the transient species (anion radical RX-. or radical pair R..Li) generated at the metal surface during attack by the halogenated derivative.
