CHLOROTRIS(TRIPHENYLPHOSPHINE)COBALT(I) Chemical Properties,Usage,Production

Reaction

Cobalt(I)-catalyzed, steroselective olefination of alkylzinc reagents with aryl aldehydes.
Reagent for the reductive radical dimerization of 3-haloindoline derivatives.
Cobalt-catalyzed, asymmetric addition of silylacetylene to 1,1-disubstituted allenes.

Description

Chlorotris(triphenylphosphine)cobalt is a monovalent cobalt complex; homogeneous catalyst for hydrogenation and hydrodimerization of alkenes; strong nucleophile, reacting with alkyl acyl halides to afford coupling products; useful for the preparation of organocobalt complexes.

Uses

A stoichiometric reducing agent that is used in the radical dimerization of halogenated organic molecules.

Uses

A stoichiometric reducing agent employed in the radical dimerization of halogenated organic molecules.

Preparation

Preparative Methods of Chlorotris(triphenylphosphine)cobalt: a solution of Cobalt(II) Chloride hexahydrate (0.6 g, 2.5 mmol) and Triphenylphosphine (2.0 g, 7.6 mmol) in EtOH (70 mL) was treated under N2 and stirring with a solution of Sodium Borohydride (0.08 g, 2.1 mmol) in EtOH at 30-40 °C; the resulting brown-green precipitate was washed several times with EtOH and water and dried (yield 92%);^[1] reductions with powdered Zn, and electrolysis, are equally effective methods; corresponding Br and I complexes are prepared similarly from CoBr2 and CoI2.

reaction suitability

core: cobalt
reagent type: catalyst

storage

Chlorotris(triphenylphosphine)cobalt is fairly stable in air; it has been stored under N2 atmosphere over several months at rt.
