Abstract

The aim of this study is to synthesize the corresponding aromatic acetylenic alcohols by alkylation with phenylacetylene in a complex catalytic system based on Zn(OTf)₂ and TBAF·3H₂O for the first time with benzaldehyde and some of its halogen derivatives. The selectivity and stability of catalysts used for the yields of reactions for the synthesis of aromatic acetylene alcohols were analyzed. The effect of benzaldehyde and its halogenated derivatives on the product yield was analyzed. The nature, structure, isomerism, spatial structure and other properties influenced to this reactions were studied. Some features of reactions of synthesis of aromatic acetylene alcohols such as stages, activation energies, kinetics of chemical changes were determined, reaction mechanisms were proposed, the most optimal conditions for alkylation reactions were found. The synthesized aromatic acetylene alcohols were identified. Their several properties such as purity, composition, structure, specific and quantum chemical constants were proved using modern physicochemical research methods. A series of relative efficiencies of aromatic acetylene synthesis based on benzaldehyde and some of its derivatives in the selected catalytic system has been proposed.
