METHOD FOR PRODUCING COMPLEX SOLUTIONS OF COPPER ACETYLENIDES USING ZIRCONIUM SALT Russian patent published in 2017 - IPC C07F19/00 C07F1/08 C07F7/00

Abstract RU 2626652 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the chemistry of complex compounds of zirconium salts with organic compounds, namely to a method for producing complex solutions of copper acetylides of formula RC≡C-Cu⋅3Z, where R is alkyl, aryl, Z - ZrOCl₂⋅8H₂O, in a bipolar aprotic solvent (N,N-dimethylformamide, N,N-dimethylacetamide) under normal conditions for 25-30 minutes. Herewith the solution is produced from copper acetylide of general formula R-C≡C-Cu and tetrahydroborate Z at a molar ratio of copper acetylides: Z=1:3. The produced solutions of copper acetylides can be used as catalysts or starting compounds for the preparation of catalysts, and also as reagents for the dissolution of copper acetylides.

EFFECT: increasing the yield.
