METHOD OF PRODUCING PHENYLETHYNYL DERIVATIVES OF AROMATIC COMPOUNDS

摘要

FIELD: chemistry.SUBSTANCE: method includes heating a mixture of components - 0.01 mol phenylacetylene, 0.01 mol iodobenzene (aryl iodide), 0.0006 g copper nanopowder and 0.002 g CuI at temperature of 110-120°C for 3 hours; after cooling, the reaction mass is poured into 100 ml cold water while stirring, followed by extraction with ethyl acetate, purification on a column with silica gel, elution with a solvent mixture with ratio of ethyl acetate to hexane of 1:6 and then distilling off the solvent to obtain pure products.EFFECT: use of the present method enables to obtain end products with high output with considerable simplification of the process.1 tbl
