ω-Monofluoroalkylrhodoximes: Synthesis and structures of [Rh{(CH2)nF}(dmgH)2(PPh3)] (n=1, 3) and C-F activation reactions

[Rh(dmgH)2(PPh3)]- ([Rh]-), synthesized by reduction of [Rh]-Cl with NaBH4 in methanolic KOH, reacts with 1,ω-dihaloalkanes X(CH2)nF (X=Cl, n=1; X=Br, n=3) forming [Rh]-CH2F (2a) and [Rh]-(CH2)3F (2b). Reaction of [Rh]- with BrCH2CH2F affords instead of the expected 2-fluoroethyl complex the dinuclear complex [Rh]-CH2CH2-[Rh] (4) exhibiting an unexpected C-F bond activation. Complexes 2a and 2b were fully characterized by NMR spectroscopy (1H, 13C, 31P, 19F) and by X-ray diffraction. Complex 2a crystallizes as a dimer with crystallographically imposed Ci symmetry. The monomeric entities are linked via two O-HO hydrogen bridges. Complex 2b is monomeric in solid state. In both complexes there is a nearly linear P-Rh-C moiety. Structural and NMR trans influence of fluoromethyl and 3-fluoropropyl ligand is discussed.
