| abstract | FIELD: chemistry of metalloorganic compounds, chemical technology. n SUBSTANCE: invention relates to methods for synthesis of novel organomagnesium compounds. Method involves interaction of disubstituted acetylenes with butylmagnesium bromide in the presence of a catalyst in argon atmosphere, under atmosphere pressure and temperature ~20 0 C, in ether solvent for 3 h followed by vacuum evaporation of ether, addition of maleic anhydride at temperature -5 0 C and stirring the reaction mass at temperature ~20 0 C in toluene medium for 6-8 h. The yield of the end product is 48-57%. Proposed method provides preparing compound of the formula (1): wherein R means ethyl (Et), n-propyl (n-Pr), n-butyl (n-Bu) with high selectivity. Synthesis of these compounds is not describes in special literature. Synthesized compounds can be used in fine organic and metalloorganic synthesis and as co-catalysts in processes of oligo- and polymerization of olefins and coupled dienes. n EFFECT: improved method of synthesis. n 1 tbl, 10 ex |
