FIELD: chemistry.SUBSTANCE: invention relates to method of obtaining complex solutions of copper acetylenides of general formula R-C?C-Cu·3MX, where R = alkyl, aryl; M = Mg, Ca; X = Cl, Br, I. Complex solution of said copper acetylenides is prepared by boiling for 1.5-2 hours in flow of inert gas of mixture, consisting of copper protoxide (CuO), water-free salt of alkali earth metal MX, where M = Mg, Ca; X = Cl, Br, I, and alkyne of general formula R-C?C-H, where R=alkyl, aryl, in molar ratio:CuO : MX: alkyne = 1.1:3:1 in bipolar aprotic solvent (H,H-dimethylformamide, N,N-dimethylacetamide) in presence of catalytic quantity of triethylamine.EFFECT: invention makes it possible to exclude stage of preparing explosive copper acetylenides and simplify technology.2 ex |
