Bis(cyclopentadienyl)cobalt(III) hexafluorophosphate
Bis(cyclopentadienyl)cobalt(III) hexafluorophosphate (CAS 12427-42-8), commonly called cobaltocenium hexafluorophosphate, is the air-stable salt of the 18-electron cobaltocenium sandwich cation paired with the hexafluorophosphate anion. With molecular formula C10H10CoF6P and a molar mass of 334.08 g/mol, it is a redox-active organometallic reagent. Tech Serve Solutions supplies it at 98% assay for use as a cocatalyst, an electrode-modification reactant and a building block for cobaltocenium-containing polymers.

Cocatalyst in palladium-catalysed coupling
Used as a cocatalyst for the Heck reaction of aryl iodides with alkenes under palladium catalysis in aqueous media. It supports carbon-carbon bond formation in cross-coupling chemistry.
Modification of organometallic electrode surfaces
Serves as a reactant for the functionalisation of organometallic electrode surfaces through cathodic reduction, exploiting the well-defined cobaltocenium/cobaltocene redox couple.
Cobaltocenium-containing polymers
Acts as a reactant in the synthesis and solution self-assembly of side-chain cobaltocenium-containing block copolymers, enabling redox-active and metallopolymer materials research.
Redox reagent and reference
As an isolable, robust 18-electron cation, the cobaltocenium ion is a recognised redox-active reagent in organometallic and electrochemical chemistry. Such uses should be confirmed against your own protocols.
