Reactivity of tri(2-furyl)phosphine (PFu3) with [Mn2(CO)10–n(NCMe)n] (n = 0–2): X-ray Structure of mer-[Mn(CO)3(η1-C4H3O)(PFu3)2]

Reaction of tri(2-furyl)phosphine (PFu3) with [Mn2(CO)10−n(NCMe)n] (n = 1, 2) at room temperature furnished the substituted complexes [Mn2(CO)10−n(PFu3)n] (1–2). Direct reaction between Mn2(CO)10 and PFu3 in refluxing toluene also afforded 2 together with mer-[Mn(CO)3(η1-C4H3O)(PFu3)2] (3) resulting from phosphorus–carbon bond cleavage of the phosphine. All three new complexes have been characterized by spectroscopic data together with single crystal X-ray diffraction studies for 3.
