General Description
Cyclobutane-1,3-dicarboxylic acid is a chemical compound with the molecular formula C6H8O4. It is a cyclic dicarboxylic acid, meaning it has two carboxylic acid functional groups attached to a four-membered cyclobutane ring. cyclobutane-1,3-dicarboxylic acid has potential use as a building block in organic synthesis and as a monomer in the production of polymers and resins. It is also used as a cross-linking agent in the synthesis of organic materials and can be used as a precursor in the manufacture of pharmaceuticals and agricultural chemicals. Additionally, this compound has been studied for its potential biological and pharmacological activities.
Check Digit Verification of cas no
The CAS Registry Mumber 2398-16-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2398-16:
(6*2)+(5*3)+(4*9)+(3*8)+(2*1)+(1*6)=95
95 % 10 = 5
So 2398-16-5 is a valid CAS Registry Number.

On the Reduction of Benzvalene Ozonide to cis-1,3-Cyclobutanedimethanol with LiAlH4

On treatment with LiAlH4 at -30 deg C the polymeric ozonide of benzvalene (1) gives bicyclobutane-endo,endo-2,4-dimethanol (7).At higher temperatures cis-1,3-cyclobutanedimethanol (4) is formed.The stereochemical course of this unusual C-C hydrogenolysis has been elucidated by means of deuterated substrates.For this purpose a complete analysis of 1H NMR spectra of the labeled cis-1,3-cyclobutanedicarboxylic anhydrides 9a-c had to be carried out.The dialcohol 7 and its bismethyl ether 16 add thiophenol across the central bond to form the cis products 18 and 19, respectively.Acids or Ag+ ions isomerize 7 via cleavage of a lateral bond into the ethers 21.
