Catalytic Reaction with Benzoic Acid Phenylacetylene in the Presence of Complex Catalysts

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.
