The conductance behaviour of NaBPh₄ in acetonitrile–toluene mixtures at 15,25, and 35 °C

Nikolaos Papadopoulos¹

Abstract: The limiting molar conductances and association constants for NaBPh, have been evaluated in acentonitrile-toluene mixtures at 15, 25, and 35°C. Experimental data have been analysed by the Lee-Wheaton conductance equation. The thermodynamic parameters of the non-coulombic interaction have been evaluated.

Electrical conductance measurements are reported for tetraethylammonium bromide (Et4NBr), tetrapropylammonium bromide (Pr4NBr), tetrabutylammonium bromide (Bu4NBr), and tetrapentylammonium bromide (Pen4NBr) in methanol, acetonitrile, and methanol (1) + acetonitrile (2) binary mixtures at 298.15 K. The conductance data have been analyzed by the Fuoss conductance−concentration equation in terms of the limiting molar conductance (Λ°), the association constant (K A), and the distance of closest approach of ions (R). The results have been interpreted in terms of ion−ion and ion−solvent interactions.

Electrical conductance measurements are reported for tetrahexylammonium bromide (Hex 4 NBr), tetraheptylammonium bromide (Hep 4 NBr), and tetrabutylammonium tetraphenylborate (Bu 4 NPh 4 B) in methanol, acetonitrile, and methanol (1) + acetonitrile (2) binary mixtures at 298.15 K. The conductance data have been analyzed by the Fuoss conductance-concentration equation in terms of the limiting molar conductance (Λ°), the association constant (K A ), and the distance of closest approach of ions (R). Singleion conductivities have been determined on the basis of tetrabutylammonium tetraphenylborate as the reference electrolyte. The results have been interpreted in terms of ion-ion and ion-solvent interactions.

Iron-Assisted Nucleophilic Aromatic Substitution on Solid Phase

2002

View full text Add to dashboard Cite

Iron-assisted S(N)Ar reactions were performed for the first time on solid phase, and a library of 36 unsymmetrically substituted phenylpiperazines and phenyl-1,4-diazepanes was synthesized with this novel strategy. The scope of iron-assisted S(N)Ar reactions on solid phase was investigated, and reactions of representative nucleophiles from groups VI (O, S, and Se) and V (N and P) of the periodic table were examined. Decomplexation of resin-bound iron complexes was achieved with 1,10-phenanthroline under irradiation, thereby overcoming the notorious disadvantages of decomplexation observed in solution-phase chemistry.
