Abstract
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.
