FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of preparing complex solutions of copper acetylenides of general formula R-CëC-Cu3MX2, where R = alkyl, aryl; M = Mg, Ca; X = Cl, Br, I in a bipolar aprotic solvent (N,N-dimethyl formamide, N,N-dimethyl formamide). The complex solution of said copper acetylenides is prepared under normal conditions from copper acetylenides of general formula R-CëC-Cu, where R=alkyl, aryl and an anhydrous salt of an alkali-earth metal MX2, where M= Mg, Ca; X = Cl, Br, I in molar ratio 1:3 for 20-30 minutes. ^ EFFECT: avoiding poisonous and expensive reagents, simple technology. ^ 1 cl, 2 ex |
