Series of functionalized organolithium compounds were prepared and added to chiral bicyclic ketones (1R-(+)-camphor analogue 2 and 1R-(−)-fenchone 3), resulting in the preparation of a small “library” of chiral aminoalcohols able to serve as ligands in metal mediated asymmetric synthesis. The configuration of the chiral ligands was approved by applying advanced NMR experiments. The absolute configurations...
The synergistic solvent extraction of five selected lanthanoid ions (La 3+ , Nd 3+ , Eu 3+ , Ho 3+ and Lu 3+ ) with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (HL) and 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis-(dimethylphosphinoylmethoxy)calix[4]arene, (S) in CHCl 3 has been studied. It was found that in presence of this phosphorus-containing...
