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.

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.
