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.
