The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid( cas:560-09-8 ) is researched.Recommanded Product: 560-09-8.Su, Zhi; Lv, Gao-Chao; Fan, Jian; Liu, Guang-Xiang; Sun, Wei-Yin published the article 《Homochiral ferroelectric three-dimensional cadmium(II) frameworks from racemic camphoric acid and 3,5-di(imidazol-1-yl)benzoic acid》 about this compound( cas:560-09-8 ) in Inorganic Chemistry Communications. Keywords: crystal structure cadmium imidazolylbenzoate D L camphorate; cadmium imidazolylbenzoate camphorate enantioselective preparation ferroelectricity CD luminescence. Let’s learn more about this compound (cas:560-09-8).
Two three-dimensional (3D) chiral frameworks, [Cd6(L)4(D-Cam)4(H2O)4]·2H2O (1D) and [Cd6(L)4(L-Cam)4(H2O)4]·2H2O (1L) [HL = 3,5-di(imidazol-1-yl)benzoic acid, D-H2Cam = D-camphoric acid, L-H2Cam = L-camphoric acid], were synthesized under hydrothermal conditions, which represent a nice example of enantioselectivity of organic racemic ligands (DL-camphorates) during the self-assembly process and formation of the metal complexes. Compounds 1D and 1L feature 3-dimensional framework with chiral chains constructed by Cd(II) cations and camphorate anions. Solid-state CD spectra of 1D and 1L revealed that they are enantiomers. Also, the complexes with chiral C2 space group display ferroelec. behavior with a remnant elec. polarization (Pr) of ∼0.140 μC/cm2 and an elec. coercive field (Ec) of ∼17.11 kV/cm.
