COBALTOCENE HEXAFLUOROPHOSPHATE Usage And Synthesis

Chemical Properties

yellow powder

Uses

Uses:

• Cocatalyst for Heck reaction of aryl iodides with alkenes using palladium as catalyst in water
• Reactant for modification of organometallic electrodes surfaces through cathodic reduction
• Reactant in synthesis and solution self-assembly of side-chain cobaltocenium-containing block copolymers

Synthesis

Cobaltocene hexafluorophosphate is readily synthesized from cobalt(II) salts + CpNa, followed by air + HPF6 or NH4PF6. Salts with a wide range of other counterions may be obtained similarly. The cobaltocenium ion^[1] may be precipitated from aqueous solution by a variety of large anions. In addition to PF6 -, convenient counterions include Br3 - and I3 -. The simple halides are hygroscopic, but may be obtained in anhydrous form by removal of water under vacuum.

Precautions

COBALTOCENE HEXAFLUOROPHOSPHATE is very stable; irritant.
