METHOD OF OBTAINING COMPLEX SOLUTIONS OF COPPER ACETYLENIDES Russian patent published in 2015 - IPC C07F1/08 C07F3/02 C07F3/04 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining complex solutions of copper acetylenides of general formula R-C≡C-Cu·3MX₂, 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 (Cu₂O), water-free salt of alkali earth metal MX₂, where M = Mg, Ca; X = Cl, Br, I, and alkyne of general formula R-C≡C-H, where R=alkyl, aryl, in molar ratio:Cu₂O : MX₂ : 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.
