Reactions of triflate complex (η5-C5H5)Re(NO)(PPh3)(OTf) (6), chlorobenzene complex [(η5-C5H5)Re(NO)(PPh3)-(ClC 6H5)]+BF4-, and tetrahydrofuran complex [(η5-C5H5)Re(NO)(PPh 3)(THF)]+BF4- with (Me2N)3S+[SiMe3F2] - give fluoride complex (η5-C5H5)Re(NO)(PPh3)(F) (3) in ≥95% NMR yields. Analytically pure 3 can be isolated from the last reaction in 65-75% yields, but decomposes on the time scale of hours in solution. The reaction of 3 with BF3·OEt2 (-95 to -40°C) gives the dichloromethane complex [(η5-C5H5)Re(NO)(PPh3)(ClCH 2Cl)]+BF4- (1), and that with MeOTf gives 6 and MeF. Reaction of 3 and P(p-tol)3 gives mainly the fluoride ligand substitution product [(η5-C5H5)Re(NO)(PPh 3)(P(p-tol)3)]+X-. Reaction of 1 and H2O gives the water complex [(η5-C5H5)Re(NO)(PPh3)(OH 2)]+BF4- (4+BF4-, 87%), which in turn reacts with CH3CN (3 equiv) to give [(η5-C5H5)Re(NO)(PPh3)(NCCH 3)]+BF4- and H2O. Reaction of (η5-C5H5)Re(NO)(PPh3)(H) with Ph3C+PF6- and then H2O gives 4+PF6- (91%). Reaction of (η5-C5H5)Re(NO)(PPh3)(CH 3) and aqueous HF appears to give water complex 4+X- (X- = F- or HF2-). Complex 3 is inert to water, but converts to 4+X- in the presence of HF or HBF4·OEt2.
