Abstract
The reactivity of [ReOCl3(PPh3)2] towards o-toluidine, m-toluidine, o-fluoroaniline, m-fluoroaniline, p-bromoaniline, p-chloroaniline and p-anisidine was examined and novel rhenium(V) imido complexes [Re(NC6H4R)Cl3(PPh3)2] (R = o-Me, m-Me, o-F, m-F, p-Cl, p-Br, p-OMe) were obtained. The resulting products were characterized by elemental analysis, electrospray ionization high-resolution mass spectrometry (ESI-HRMS), 1H, 13C{1H}, 19F{1H} and 31P{1H} NMR, FT-IR spectroscopy, and X-ray crystallography. For m-toluidine, m-fluroaniline and p-chloroaniline, rhenium(V) imido-amino mononuclear [Re(NC6H4R)Cl3(H2NC6H4R)(PPh3)] (R = m-F, p-Cl) complexes and binuclear [{Re(m-NC6H4Me)Cl2(m-H2NC6H4Me)(PPh3)}2O] complex were isolated as side products and characterized by X-ray crystallography. All six-coordinate rhenium(V) complexes display distorted octahedral coordination geometry.
