Dicyclohexylchlorophosphine Usage And Synthesis

Chemical Properties

clear colorless liquid

Uses

Dicyclohexylchlorophosphine is used as pharmaceutical intermediate. It is also used in the synthesis of various phosphines.

Uses

Chlorodicyclohexylphosphine can be used as a reactant in the synthesis of:

• 1,2-Bis(dicyclohexylphosphinoxy)ethane ligand by reacting with ethylene glycol in the presence of triethylamine via Michaelis?Arbuzov type rearrangements.
• 1,1,2,2-tetracyclohexyldiphosphine monosulfide ligand by treating with LiS.

It can be also used as a starting material for the preparation of some other ligands such as dicyclohexylphosphine oxide , phosphino substituted N-aryl pyrroles , di-tert-butyl((dicyclohexylphosphino)methyl)phosphine , dicyclohexylcyclopentylphosphine. These ligands are used in Pd-catalyzed cross-coupling reactions.

Precautions

Store in cool, dry conditions in well sealed containers. Protect from humidity and water. Store under dry inert gas. It is sensitive to air and moisture. Incompatible with strong oxidizing agents.
