摘要

The reactions of [ReCl₃(CH₃CN)(PPh₃)₂] with benzil PhC(O)C(O)Ph, and with a natural 1,2-naphthoquinone derivative, β-lapachone (Lap), result in oxidative addition with the formation of Re(V) complexes with stilbenediolate, [ReCl₃(PhC(O)C(O)Ph)(PPh₃)] (1) and with a reduced semiquinonic form of lapachone, [Re^IVCl₃(Lap⁻)(PPh₃)] (2). The structures of both compounds were established by X-ray crystallography.
