Application

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.

This protocol describes the synthesis of a representative example of the electron-rich biaryl-like KITPHOS class of monophosphine, 11-dicyclohexylphosphino-12-phenyl-9,10-dihydro-9,10-ethenoanthracene (H-KITPHOS). The bicyclic architecture of H-KITPHOS is constructed via [4+2] Diels-Alder cycloaddition between 1-(dicyclohexylphosphinoylethynyl)benzene and anthracene. H-KITPHOS monophosphine is prepared via an
