The crystal structure of Zn(TPPO).2BF4 (TPPO = triphenyl phosphine oxide) has been determined by single-crystal X-ray diffraction: the zinc atom coordination polyhedron is a slightly distorted tetrahedron ([Zn-O] = 1.905 angstrom, [O-Zn-O] = 109.5-degrees); three Zn-O-P angles are ...
A novel triphenylphosphine-contained poly(ether ether ketone ketone) was synthesized from bis[4-(p-fluorobenzoyl)-phenyl]phenylphosphine oxide and hydroquinone by nucleophilic copolycondensation with sulfolane as the solvent. The structure was confirmed via FTIR, 31P NMR and 1H NMR. Electrical property...
Tripodal phosphine oxidecomplexesf-elementsIRNMRA new tripodal O-donor ligand, tris(2-N,N-dibutylcarbamoylmethoxyphenyl)phosphine oxide (L), was synthesized. This potentially tetradentate ligand L exhibits variable denticity upon complexation with UO2(NO3)2, Nd(NO3)3, and Lu(NO3)3. The ...
Synthesis of isothiocyanatophosphoranes and isothiocyanatophosphonium salts via oxidative addition of thiocyanogen and ligand substitution: Novel reagents ... The oxidative addition of thiocyanogen to triphenylphosphine has been investigated by 31P NMR spectroscopy showing the formation of the isothio...
and its oxidation product, sodium triphenylphosphine-m-sulfonate oxide (TPPMSO), can be easily separated and recov- ered from the reaction mixture by precipitation with a non-polar solvent, without the need for tedious chromatography as is usually required for the removal of triphenylphosphine oxide...
