Název v původním jazyce

Halogen protected cobalt bis(dicarbollide) ions with covalently bonded CMPO functions as anionic extractants for trivalent lanthanide/actinide partitioning

Popis výsledku v původním jazyce

Halogen protected CMPO derivatives of the cobalt bis(dicarbollide) ion (1) were synthesized with the aim to develop efficient extraction agents with increased stability for liquid?liquid extraction of lanthanides and actinides from high-level activity nuclear waste. New halogen protected compounds of the general formulation [3,3-Co(III)-(8-CMPO-(CH2-CH2O)2-1,2-C2B9H10)(8-X-1,2-C2B9H10)] (where X = Cl, Br, I; CMPO = Ph2P(O)-CH2C(O)(t-C8H17)N-) (4a?c), were prepared and studied for Ln(III)/An(III) group extraction. These compounds were accessible via halogenated zwitterionic amino derivatives [3,3-Co(III)-(8-t-C8H17NH2-(CH2-CH2O)2-1,2-C2B9H10)(8-X-1,2-C2B9H10)] (3a?c), prepared by several different synthetic methods. All the compounds were characterizedby a combination of 11B NMR, 1H high field NMR, ESI-MS, HPLC and other methods. The effect of the halogen in the structures of 4a?c on the extraction properties is outlined. In general, these compounds preserve good extraction efficiency
