Phosphorus-containing podands
Autor: V. I. Evreinov, E. N. Tsvetkov, Z. N. Vostroknutova, V. E. Baulin
Publikováno v: Russian Chemical Bulletin. 42:472-477
An improved preparative method for the synthesis of oligo(ethylene glycol) bis[2-(diphenylphosphinoyl)ethyl] ethers has been developed. The complex-forming ability of these ligands toward alkali-metal cations has been studied by conductometry in anhy
