The fulvene complexes [(η6-C5Me4CH2)Re(CO)2(R)] (1a, R{double bond, long}I; 1b, R{double bond, long}C6F5) react at the exocyclic methylene carbon with a vinylmagnesium bromide solution to produce the anionic species [(η5-C5Me4CH2CH{double bond, long}CH2)Re(CO)2(R)]-. Protonation with HCl at 0 °C produces the hydride complexes [trans-(η5-C5Me4CH2CH{double bond, long}CH2)Re(CO)2(R)(H)] (2a, R{double bond, long}I; 2b, R{double bond, long}C6F5). Thermolysis of an hexane solution of the iodo-hydride (2a) under a CO atmosphere yields the complex [(η5-C5Me4CH2CH{double bond, long}CH2)Re(CO)3] (3) and [Re(CO)5I] as by-product. Thermolysis of 2b produced three new products, mainly the chelated complex [(η5:η2-C5Me4CH2CH{double bond, long}CH2)Re(CO)2] (4) and complex 3, with a non-coordinated olefin group, in moderated yield, and traces of [Re(CO)5(C6F5)]. Thermolysis of an hexane solution of 2 in presence of an excess of PMe3, afforded the phosphine derivative [(η5-C5Me4CH2CH{double bond, long}CH2)Re(CO)2(PMe3)] (5). All the complexes were characterized by IR, 1H, 13C and 31P NMR spectroscopies and mass spectrometry. The molecular structure of 4 has also been determined. The molecule exhibits a formal three-legged piano-stool structure, with two CO groups, and the third position corresponding to the η2-coordination of the propenyl side arm of the η5-C5Me4 ring.

Pentacarbonyl perfluoroorgano manganese and rhenium compounds M(CO)5Rf (M=Mn, Re; Rf=CF3, C2F5, C3F7, C4F9, C6F13, C6F5) are formed as colourless solids or liquids in good yields from the reactions of M(CO)5Br with Cd(Rf)2 complexes in CH2Cl2 eihter in the presence of stoichiometric amounts of Ag[BF4] or catalytic amounts of CuI. In the presence of e.g. CH3CN the mono or disubstituted complexes M(CO)4(CH3CN)Rf of M(CO)3(CH3CN)2Rf are formed.
