SYNTHESIS AND PROPERTIES OF ADDITION COMPOUNDS BETWEEN TRIPHENYLPHOSPHINE-OXIDE(TPPO) AND LANTHANIDE TRIFLUOROMETHANESULFONATES

SYNTHESIS AND PROPERTIES OF ADDITION COMPOUNDS BETWEEN TRIPHENYLPHOSPHINE-OXIDE(TPPO) AND LANTHANIDE TRIFLUOROMETHANESULFONATES

Additon compounds between triphenylphosphine-oxide and trifluoromethanesulfonates are synthesized and characterized by microanalyses, electrolytic conductance, vibrational (infrared) spectra, absorption spectra in the visible region and thermogravimetric procedures. The results are in agreement with...

Zusammenfassung:Additon compounds between triphenylphosphine-oxide and trifluoromethanesulfonates are synthesized and characterized by microanalyses, electrolytic conductance, vibrational (infrared) spectra, absorption spectra in the visible region and thermogravimetric procedures. The results are in agreement with the formulas La(CF 3 SO 3 ) 3 3TPPO 4H 2 O and Ln(CF 3 SO 3 ) 3 ·4TPPO. The ligands (TPPO) coordinate through the phosphoryl oxygen. Complex interactions with solvents of different donating capacities are also found. Thermogravimetric studies result in lanthanide trifluoride products.
