Abstract
The new heterofunctionalized phosphane [(1R,2R)-N-(2-aminocyclohexyl)]-2-(diphenylphosphanyl)benzamide (L1), N-(2-aminoethyl)-2-(diphenylphosphanyl)benzamide (L2) and 2-(diphenylphosphanyl)-N-(2-hydroxyethyl)benzamide (L3) were synthesized by reaction of N-[2-(diphenylphosphanyl)benzoyloxy]succinimide (3) in dichloromethane with (1R,2R)-(−)-diaminocyclohexane, ethylenediamine and ethanolamine, respectively. Reactions of [Re(O)Cl4]− with L1, L2and L3, at a 1:1 metal/ligand molar ratio gave neutral trichlorooxorhenium(V) complexes of the type [Re(O)Cl3{κ2-L}] [L = L1 (4), L2 (5), L3 (6)]. The characterization of the compounds involved IR, 1H- and 31P-NMR spectroscopy, and X-ray crystallographic analysis for L1, 5 and 6. The Re atom is sixcoordinate in complexes 4−6, with an oxo ligand, three chloride ligands and a neutral bidentate heterofunctionalized phosphane ligand.
