Haddadin, M. J.; Higuchi, T.; Stella, V. published an article about the compound: cis-Cyclohexane-1,2-dicarboxylic acid( cas:610-09-3,SMILESS:O=C([C@H]1[C@@H](C(O)=O)CCCC1)O ).Product Details of 610-09-3. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:610-09-3) through the article.
The reversible reactions of several cyclic anhydrides with HOAc to form Ac2O and the corresponding dicarboxylic acid, catalyzed by HClO4 at 25°, were studied. The equilibrium constants calculated from spectral data, were 4.85 × 10-4, 1.08 × 10-1, and 4.6 × 10-1 M for succinic, trans-1,2-cyclohexanedicarboxyllic, and glutaric anhydrides, resp. Maleic, phthalic, and cis-1,2-cyclohexanedicarboxylic anhydrides did not undergo any detectable reaction with HOAc under these conditions, suggesting still higher stability. The reverse rate constants were relatively independent of the structure of the attacking diacid, while the forward rate constants were found to parallel the equilibrium constants The rate-determining step for the forward reaction appears to be the breakdown of the tetrahedral intermediate formed by the attack of HOAc mol. on the protonated cyclic anhydride.
This literature about this compound(610-09-3)Product Details of 610-09-3has given us a lot of inspiration, and I hope that the research on this compound(cis-Cyclohexane-1,2-dicarboxylic acid) can be further advanced. Maybe we can get more compounds in a similar way.
