MeCl chem.-ionization mass spectroscopy, involving a methylation technique based on the chem. resolution of H migrations, gives ionic fragments which differentiate cis and trans isomers. The method differentiates 1,2-cyclohexanedicarboxylic acids but fails (as do protonation methods) to differentiate 1,2-cyclohexanediols. The utility of methylation in conjunction with mass spectra/mass spectra techniques in distinguishing the regioisomerism of HOC6H4CO2H is discussed.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: cis-Cyclohexane-1,2-dicarboxylic acid( cas:610-09-3 ) is researched.Synthetic Route of C8H12O4.Chandramalar, A. V. M.; Lim, Y. Y.; Leong, Y.

Keywords: configuration effect cyclohexanecarboxylic acid zirconia colloidal force; yield stress pH zirconia cyclohexanecarboxylic acid configuration effect. Let’s learn more about this compound (cas:610-09-3).

The effects of cis- and trans-1,2-, trans-1,4-cyclohexanedicarboxylic acid, 95% cis-1,3,5-cyclohexane tricarboxylic acid and cis-1,2,3,4,5,6-cyclohexanehexacarboxylic acid on the yield stress-pH behavior of concentrated ZrO2 dispersions are reported. Adsorbed cis-1,2,3,4,5,6-cyclohexanehexacarboxylic acid imparts predominantly steric interactions. It forms a steric barrier keeping the interacting particles apart. Adsorbed cis- and trans-1,2 increase the maximum yield stress and this was attributed to a hydrophobic force resulting from the part of the cyclohexane ring sticking out into the solution which is devoid of charged or hydrophilic group. Adsorbed trans-1,4 increases the maximum yield stress by ≥3-fold and its configuration favors strong bridging interaction with an adjacent particle. Predominantly, cis-1,3,5 also increases the maximum yield stress but only by 60% at the same additive concentration This was attributed to a smaller degree of bridging.

The trinuclear cluster Ni3(μ3-I)2(dppm)3, (1) [dppm = bis(diphenylphosphino)methane] is formed by conproportionation of Ni(COD)2 and NiI2 in the presence of dppm. Cluster 1 and its singly oxidized radical cation (2) have been characterized spectroscopically and by x-ray diffraction. Cluster 2 exhibits a slight Jahn-Teller distortion of its triangular nickel framework. Irradiation of 1 in the presence of CO2 results in photochem. electron transfer to produce CO2•- and 2. The CO2•- can be trapped by H-atom abstraction from toluene to produce formate ion or with cyclohexene to form cis- and trans-1,2-cyclohexanedicarboxylic acid.
