Heterofunctionalized phosphines derived from (2-formylphenyl)diphenylphosphine and their reactions with oxorhenium(V) complexes

Oxidorhenium(V) Complexes with Oxazolinylmethoxido Ligands – Structure and Catalytic Epoxidation

“…However, consistent with two isomers, the 31 P NMR spectrum of 3c in CDCl 3 revealed two resonances for a coordinated PPh 3 molecule at δ = -16.20 and -17.30 ppm, which is diagnostic of triphenylphosphane in the coordination sphere of Re V . [15,[34][35][36][37] The IR spectra of 3a-3d exhibit characteristic ν(Re=O) bands at 965.00 (3a), 974.62 (3b), 973.43 (3c) and 965.72 cm -1 (3d), which are in good agreement with those of similar oxidorhenium compounds. [8,15,34,36] The bands at 1670.05 (3a), 1644.63 (3b), 1644.59 (3c) and 1648.17 cm -1 (3d) are assigned to the ν(C=N) mode of the oxazoline ring, which represents a shift of 4-25 cm -1 to a lower frequency compared to the free ligands, indicating that the imine nitrogen atom of the oxazoline ring is strongly coordinated to the metal centre.…”

Tricarbonylrhenium(I) Complexes with Tridentate Schiff Bases

“…(NEt 4 ) 2 [Re(CO) 3 Br 3 ] was prepared from [Re(CO) 5 Br] and (NEt 4 )Br in diglyme [37,38] . HL 1 was prepared according to a literature procedure [39] …”

Manganese, technetium and rhenium

“…77 78 Meanwhile, Re(V) complexes have been prepared with Schiff bases derived from (2-formylphenyl)diphenyphosphine and 2-aminophenol and their chemistry studied. 79 Hydrogen exchange of rhenium(VII) heptahydridobis(triphenylphosphine) with a range of solvents and itself has been investigated. 80 A range of rhenium carbonyltrifluoroacetate complexes containing phosphites, phosphonites and phosphinite ligands have been prepared and the trifluoroacetate ligand found to act in a monodentate manner.…”
