METHOD OF PREPARING COMPLEX SOLUTIONS OF COPPER ACETYLENIDES Russian patent published in 2011 - IPC C07F1/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of preparing complex solutions of copper acetylenides of general formula R-C≡C-Cu·3MX₂, 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-C≡C-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.
