METHOD OF PRODUCING HETEROANNULAR 1,1' BIS-(TRIORGANOSILYL)FERROCENES Russian patent published in 2024 - IPC C07F17/02 

FIELD: chemistry.

SUBSTANCE: invention relates to heteroannular disubstituted ferrocene derivatives, specifically to a method of producing heteroannular disubstituted tri (organosilyl) ferrocenes. Method involves reaction of 1,1'-dilithium-ferrocene with trialkylchlorosilanes in an inert solvent, followed by extraction of desired products. Low-boiling hydrocarbons, mixtures of hydrocarbon solvents are used as inert solvents, trimethylchlorosilane, methyldiethylchlorosilane or triethylchlorosilane are used as trialkylchlorosilanes, dosage of trialkylchlorosilanes is carried out at temperature of 10-15 °C.

EFFECT: method increases output of trialkylsilyl ferrocenes while reducing power consumption of the process.
