“…Alternatively, vinyl transfer from vinyl acetate to aliphatic, aromatic, and heteroaromatic alcohols and acids has provided a safe and efficient synthesis of corresponding vinyl esters without catalysts by the reaction of vinyl acetate on carboxylic acids is an important task. Incorporating the vinyl group of vinyl acetate into aliphatic, aromatic, and heteroaromatic acids provides safe and efficient methods of synthesizing vinyl esters [14].…”

In this work, the reaction of derivatives of benzoic acid containing substituents in the aromatic ring (1a-o) with 2-chloro-4,6dimethoxy-1,3,5-triazine (4) in the presence of N-methylmorpholine (6) has been synthesized active triazine esters of carboxylic acids (3a-o). These compounds obtained in the presence of potassium butylate (7) in reaction with vinyl acetate (2) have formed vinyl esters of corresponding aromatic carboxylic acids (5a-o). The electronic effect of the substitutor in the aromatic ring affects on carrying out of the reaction and the nature of obtained products. The structure of the synthesized vinyl esters of aromatic carboxylic acids was confirmed by FT-IR, 1H_NMR, 13C-NMR, and LC/MS spectral analysis, and some of their physical constants were determined.

“…An analysis of the literature on new trends in the chemistry of acetylene compounds, ethynylation [1][2][3] and vinylation reactions [4][5][6], process conditions and patterns arising from them [7][8][9][10], practical and theoretical concepts shows that acetylene is a primary or secondary raw material for the thermal processing of hydrocarbons and carbon [11,12]. Acetylene is also obtained from calcium carbide.…”

This article describes a method for the synthesis of vinyl esters from fruit acids: malic, tartaric, citric and acetylene, as well as the results of a spectrophotometric analysis of the obtained compounds. Process conditions, product yields, and physicochemical properties of the resulting vinyl esters are given. The homogeneous catalytic reaction of vinylation of malic, tartaric and citric acids with acetylene has been studied and the formation of the corresponding vinyl esters has been proven. The mechanisms of vinylation reactions in the presence of acetylene are proposed. In the synthesis of vinyl ethers, the effect of pressure, temperature, and reaction time on the product yield was established.

“…In the present study vinyl esters of carboxylic acids are active compounds and are used as intermediates in organic synthesis, polymerization, hydrogenation, crossinternationalization reactions. The addition of carboxylic acids to alkynes proceeds under mild reaction conditions, in the presence of metal catalysts, with the formation of vinyl esters [1][2][3][4].…”

In this work, we studied the processes of vinyl ester formation by the addition of benzoic acid to phenylacetylene in the presence of complex catalysts of diacetate-di (2-amino-5-methylthio-1,3,4-thiadiazolo) cobalt(II) ([Co(C3H5N3S2)2(CH3COO)2] and tetrakis(2-amino-5-ethylthio-1,3,4-thiadiazole)-zinc(II) dinitrate ([Zn(C4H7S2)4](NO3)2): 1-phenylvinyl benzoate and anti-Markovnikov coupling product - styryl benzoate were obtained. The effect of the nature of solvents on the yields of products in the presence of the [Zn(C4H7S2)4](NO3)2 complex catalyst was studied. The structure of the synthesized vinyl esters was proved by IR, 1H NMR, 13C NMR spectroscopies.
