•Novel methine carbon-to-oxorhenium(V) σ bond•Sulfur abstraction by PPh3•Coordination of neutral ketonic oxygen to oxorhenium(V)•X-ray crystal structures
The reaction of trans-[ReOCl3(PPh3)2] with 1-(1,3-benzothiazol-2-yl)-3-benzoylthiourea (Hbbt) in methanol led to the isolation of the complex [ReOCl2(cbt)(PPh3)] (1). It contains the monoanionic bidentate chelate N-((benzothiazol-2-ylamino)methylene)benzamide (cbt). The new ligand cbt is coordinated via a neutral ketonic oxygen and an anionic imino-acyl carbon atom, and was formed by the abstraction of the thionyl sulfur of Hbbt by a triphenylphosphine of the starting complex, with S = PPh3 also been formed as by-product. Compound 1 was characterized by elemental analysis, FTIR, proton NMR and single crystal X-ray diffraction.
Graphical abstractThe reaction of trans-[ReOCl3(PPh3)2] with 1-(1,3-benzothiazol-2-yl)-3-benzoylthiourea (Hbbt) in methanol led to the isolation of the complex [ReOCl2(cbt)(PPh3)], which contains the monoanionic bidentate chelate N-((benzothiazol-2-ylamino)methylene)benzamide (cbt). The new ligand cbt is coordinated via a neutral ketonic oxygen and a charged imino-acyl carbon atom, and was formed by the abstraction of the thionyl sulfur of Hbbt by a triphenylphosphine of the starting complex, with S = PPh3 also been formed as by-product.Figure optionsDownload full-size imageDownload as PowerPoint slide
