Abstract

Under mild conditions [ReX(CO),(THF),] reacts with pyrazolylmethylpyridines to form the complexesfat-[ReX(CO),(BPz)] and fat-[ReX(CO),(BMPz)] (X = Cl, Br, or I; BPz = 2,6-bis(pyrazol-l-ylmethyl)pyridine ; BMPz = 2,6-bis(3,5-dimethylpyrazol-1-ylmethyl)pyridine) that involve BPz and BMPz actingas non-fluxional bidentate chelate ligands. Under more severe reaction conditions fuc-[ReX(CO),(BPz)] isconverted to@-[Re(CO),(BPz)]X (X = Cl, Br, or I). Trimethylplatinum(IV)iodide reacts with BPz to formfuc-[PtMe,(BPz)]I. The crystal structure offac-[ReI(CO)3(BMPz)] confirms the bidentate chelate bonding ofBMPz with a N-Re-N angle of 85.8”.
