Nitrosyl complexes of rhenium. Synthesis of some fluoro complexes of rhenium(I), including the novel cationic complex fluorocarbonylnitrosyltris(triphenylphosphine)rhenium(I) tetrafluoroborate

The complex previously reported as ReCl2(NO)(PPh3)2 has been reformulated as a methoxide complex, ReCl2-(OCH3)(NO)(PPh3)2. ReCl2(OCH3)(NO)(PPh3)2 reacts with NaBH4 and PPh3 in ethanol to give much improved yields of ReH2(NO)(PPh3)3. ReH2(NO)(PPh3)3 reacts with HCl in ethanol suspension to form air-sensitive ReCl2(NO)(PPh3)3, which in turn reacts with CO or CNR (R = p-tolyl) to give ReCl2(CO)(NO)(PPh3)2 and ReCl2(CNR)2(NO)(PPh3), respectively. ReH2(NO)(PPh3)3 reacts with HBF4 (or HPF6) in the presence of CO to give the novel fluoro cation [ReF(CO)(NO)(PPh3)3]+, which reacts with certain coordinating anions to give neutral ReXF(CO)(NO)(PPh3)2 (X = H, OCH3, F). ReHF(CO)(NO)(PPh3)2 is unusual in that its stereochemistry can be determined absolutely by a combination of IR and 1H NMR spectroscopy. The structure has been determined of fluorocarbonylnitrosyltris(triphenylphosphine)rhenium(I) perchlorate, prepared from [ReF(CO)(NO)(PPh3)3]BF4 and NaClO4 in ethanol. Solvated crystals of [ReF(CO)(NO)(PPh3)3]ClO4 from dichloromethane-cyclohexane are monoclinic, with a = 14.981 (2) ?, b = 25.560 (3) ?, c = 15.133 (4) ?, β = 104.84°, space group P21/n, and Z = 4. Data were collected by four-circle diffractometry with 2092 reflections with I > σ(I) being observed. Refinement was by large-block least squares to R = 0.057. The unit cell contains molecules of crystallization disordered about a center of symmetry. There appears to be a random mixture of cyclohexane and dichloromethane, and atomic locations have not been assigned to the solvent atoms. The structure of the cation is that of a distorted octahedron with a meridional array of phosphine ligands and the fluoride ligand (r(ReF) = 1.973 (13) ?) trans to the linear nitrosyl group.
