Description

Application

Potassiumhexacyanocobaltate(III) can be used as a complexing agent to synthesize double metal cyanide catalyst:

• For the chemoselective reductive amination of carbonyl compounds with aromatic amines to synthesize substituted amines in the presence of polymethylhydrosiloxane as a reducing agent.
• In the ring opening polymerization of propylene oxide to synthesize polyols.
• In the coupling reaction of CO₂ with hydrous epoxides to synthesize cyclic carbonates.
