Název v původním jazyce

Cobalt bis(dicarbollide) ions with covalently bonded CMPO groups as selective extraction agents for lanthanide and actinide cations from highly acidic nuclear waste solutions.

Popis výsledku v původním jazyce

A new series of boron substituted cobalt bis(dicarbollide) (1-) ion (1) derivatives of the general formula [(8-CMPO- (CH2-CH2O)2-1,2-C2B9H10) (1', 2'-C2B9H11)-3,3'-Co] (CMPO = Ph2P(O) - CH2C(O) NR, R = C4H9 (3b), - C12H25 (4b), - CH2-C6H5 (5b)) was prepared by ring cleavage of the 8-dioxane-cobalt bis(dicarbollide) (2) bi-polar compound by the respective primary amines and by subsequent reaction of the resulting amino derivatives (3a-5a) with the nitrophenyl ester of diphenylphosphorylacetic acid. The compounds were synthesized with the aim to develop a new class of more efficient extraction agents for liquid liquid extraction of polyvalent cations, i.e. lanthanides and actinides, from high-level activity nuclear waste. All compounds were characterizedby a combination of B-11 NMR, H-1 high field NMR, Mass Spectrometry with Electrospray and MALDI TOF ionisation, HPLC and other techniques. The molecular structure of the supramolecular Ln(3+) complex of the anion 5b was determined by sin
