“…The dimerization process of 1-ethynylcyclohexanol was conducted at 298 K for 48 h, based on a catalytic system with a copper(I) chloride catalyst, tetrachloromethane, N 1 ,N 1 ,N 2 ,N 2tetramethylethylenediamine as a ligand and ethanol as the solvent, following the general routine used by Tirkasheva et al (2022) to prepare 8,13-dimethylcosa-9,11-diyne-8,13-diol. This yielded 1,1 0 -(buta-1,3-diyne-1,4-diyl)bis(cyclohexan-1-ol) (I) as a brown liquid.…”

The title compound, C16H22O2, was synthesized in order to obtain its guest-free form because `wheel-and-axle'-shaped molecules tend to crystallize from solutions as solvates or host–guest molecules. It crystallizes in the monoclinic space group P2/c with two crystallographically non-equivalent molecules, one situated on an inversion center and the other on a twofold axis. The rod-like 1,3-diyne fragments have the usual linear geometry. In the crystal, O—H ... O bonds form eight-membered rings of the R 4 4(8) type, linking molecules into layers. The Hirshfeld surface analysis indicates that the largest contributions are from intermolecular H...H (ca 71%) and H...C/C...H (ca 19%) contacts. The energies of the frontier molecular orbitals were determined by DFT calculations at the B3LYP/def2-TZVP level of theory.

In this work by the reaction of derivatives of benzoic acid containing substituents in the aromatic ring with vinyl acetate in the presence2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) vinyl esters of aromatic carboxylic acids have been synthesized. The influence of the nature of the initial compounds, temperature, zinc trifluoromethyl-sulfonate (Zn(OTf)2), dilithium 3,3′-diphenylbinaphtholate (3,3′-Ph2BINOL-2Li), tertiary potassium butylate (KOtrBu), butyllithium (BuLi) on the yield of synthesized compounds was investigated. The structure of the synthesized vinyl esters was proved by IR, 1H NMR, 13C NMR spectroscopies

The reaction of benzoic, 4-methylbenzoic, 2-bromobenzoic and 4-bromobenzoic acids with phenylacetylene was carried out in a toluene solution at a temperature of 110 0C in the presence of a catalyst - 1 mol % [Zn(C4H7S2)4](NO3)2. In the coupling reaction of carboxylic acids with phenylacetylene a mixture of coupling products is formed according to the Markovnikov and anti-Markovnikov rules. A reaction mechanism was proposed and it was found that the yield of vinyl esters increased in the serie 4-CH3-C6H4COOH< C6H5COOH< 4-Br-C6H4COOH< 2-Br-C6H4COOH. It was found that with an increasing acidity of the carboxylic acids, the product formed by Markovnikov rule has been formed in a larger amount. On the contrary, as the acidity of the starting compounds decreased, the amount of the anti-Markovnikov coupling product has increased. The total yield of reaction products of phenylacetylene with carboxylic acid is 44% (65/35) in 4-methylbenzoic acid, 67% (80/20) in benzoic acid, 78% (82/18) in 4-bromobenzoic acid, 82% (85 /15) in 2-bromobenzoic acid. The structure of the synthesized vinyl esters was proved on the base of the analysis of IR, 1H, 13C NMR and Mass spectrums.
