Application

Cocatalyst for:
  • Nickel-catalyzed coupling reactions of alkenes, aldehydes, and silyl triflates

Catalyst for:
  • Coupling of nonactivated and deactivated aryl chlorides with arylboronic acid
  • Preparation of (alkyl)(aryl)phosphines and triarylphosphines, as mediators of rhodium-catalyzed propene and hexene hydroformylation reactions

  • Ligand for PC bond cleavage during Heck vinylation of aryl halides with Bu acrylate in presence of palladium catalyst compounds
Dicyclohexyl(2-methylphenyl)phosphine [PCy2(o-Tol)] may be used along with [IrCl(cod)]2 to form a complex that can catalyze the addition of aliphatic acid chlorides to terminal alkynes to form (Z)-β-chloro-α,β-unsaturated ketones.

General description

Dicyclohexyl(2-methylphenyl)phosphine is a phosphorus ligand with some unique features like high melting point, ease of handle and less susceptibility for oxidation, making it an ideal catalyst in coupling reactions.
