Abstract

A one-pot, atom-economic, metal- and halogen-free synthesis of functional triphosphines with nitrogen and (or) oxygen atoms­ as additional weaker coordinating sites (new hemilabile ligands) through exhaustive addition of secondary phosphines to available trivinyl ethers of aminotriols and triols has been developed. The reaction proceeds under free-radical conditions (UV irradiation or AIBN, with 3:1 reactant molar ratio) to give chemo- and regioselectively anti-Markovnikov triadducts to all three vinyloxy groups in good to excellent yields.
