Reactivity of tri(2-furyl)phosphine (Pfu 3 ) with [Mn 2 (CO) 10– n (NCMe) n ] ( n = 0–2): X-ray Structure of mer -[Mn(CO) 3 (η 1 -C 4 H 3 O)(Pfu 3 ) 2 ]

Abstract Reaction of tri(2-furyl)phosphine (PFu 3 ) with [Mn 2 (CO) 10− n (NCMe) n ] ( n  = 1, 2) at room temperature furnished the substituted complexes [Mn 2 (CO) 10− n (PFu 3 ) n ] ( 1 – 2 ). Direct reaction between Mn 2 (CO) 10 and PFu 3 in refluxing toluene also afforded 2 together with mer -[Mn(CO) 3 (η 1 -C 4 H 3 O)(PFu 3 ) 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 .
