Abstract The reactions of di-2-pyridyl ketone (dpk), 2-benzoylpyridine (zpy) and 2- hydroxybenzophenone (Hbp) with [Re (CO) 5 Cl](A) and trans-[ReOX 3 (PPh 3) 2](B, X= Cl, Br) were studied. The complex fac-[Re (CO) 3 (dpk· OCH 3)] was isolated from the reaction of A with dpk in methanol. The monoanionic tridentate chelate dpk· OCH 3 was formed by the nucleophilic attack of methanol at the carbonylic carbon atom of dpk. A similar attack of ...
