Reaction of (η5-C13H9)Mn(CO)3 with Alkylphosphines: Formation and Isolation of η1-Fluorenyl Complexes
Reaction of (η5-C13H9)Mn(CO)3 with L = PEt3 or PBu3 leads to formation of (η1-C13H9Mn(CO)3L2. The L = PEt3 complex was isolated analytically pure in moderate yield and characterized as the trans-meridional isomer by1H,31P, and13C NMR and IR spectroscopies. (η1-C13H9)Mn(CO)3L2 decomposes via Mn-C bond homolysis to the C13H9 radical and Mn(CO)3L2, which reacts further to yield HMn(CO)3L2. (η1-C13H9)Mn(CO)3L2 can also be prepared by reacting L with (η6-C13H9)Mn(CO)3, apparently via a novel η6 to η1 shift.
