Facile cyclometalation of (3-chloropropyl)dicyclohexylphosphine occurs when RhCl(COD)(C-Hx2PCH2CH2CH2Cl) is treated with the secondary-tertiary diphosphine c-Hx2PCH2CH2CH2P(Ph)H in the absence of a stronger base. On the other hand, if the same reagents are combined at -78°C in the presence of NEt3 and allowed to warm to room temperature over a 2-h period, a clean synthesis of the chelated triphosphine ligand PhP(CH2CH2CH2P-c-Hx2)2 results.
