Abstract

Irradiation of Mn₂(CO)₁₀ with the bidentate phosphine 1,2-bis(diethylphosphino)ethane (depe) rapidly yields [Mn(CO)₃depe]₂ and Mn(CO)₃depe. The two species are in equilibrium in solution, with the dimer present in larger amounts: [Mn(CO)₃depe]₂ {A figure is presented} 2Mn(CO)₃depe. The formation of Mn(CO)₃depe proceeds much more readily than the formation of Mn(CO)₃L₂ (L = monodentate phosphine complexes). In addition, no side-products are formed as is the case with the monodentate ligands. The ease with which Mn(CO)₃depe can be generated makes it a convenient reagent for the synthesis of organic radicals because the complex abstracts halogen atoms from alkyl and aryl halides: Mn(CO)₃depe + RX → Mn(CO)₃(depe)X + P.
