The new heterofunctionalized phosphane [(1 R ,2 R )‐ N ‐(2‐aminocyclohexyl)]‐2‐(diphenylphosphanyl)benzamide ( L 1 ), N ‐(2‐aminoethyl)‐2‐(diphenylphosphanyl)benzamide ( L 2 ) and 2‐(diphenylphosphanyl)‐ N ‐(2‐hydroxyethyl)benzamide ( L 3 ) were synthesized by reaction of N ‐[2‐(diphenylphosphanyl)benzoyloxy]succinimide ( 3 ) in dichloromethane with (1 R ,2 R )‐(−)‐diaminocyclohexane, ethylenediamine and ethanolamine, respectively. Reactions of [Re(O)Cl 4 ] − with L 1 , L 2 and L 3 , at a 1:1 metal/ligand molar ratio gave neutral trichlorooxorhenium(V) complexes of the type [Re(O)Cl 3 {κ 2 ‐L}] [L = L 1 ( 4 ), L 2 ( 5 ), L 3 ( 6 )]. The characterization of the compounds involved IR, 1 H‐ and 31 P‐NMR spectroscopy, and X‐ray crystallographic analysis for L 1 , 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.
