Synthesis of a di-alcohol derivative of cobalt dicarbollide for condensation polymerization
- and others
Polymers containing the cobalt dicarbollide anion in the main chain are currently of interest as possible cation exchange materials for the selective removal of {sup 137}Cs{sup +} and {sup 90}Sr{sup 2} from nuclear wastes. Suitable monomeric compounds are obtained by derivatizing the carbon sites of the cobalt dicarbollide anion with organic functional groups. Selective deprotonation of [Co(C{sub 2}B{sub 9}H{sub 11}){sub 2}] with 2 equivalent of nBuLi in the results in the formation of the dilithio complex, [Co(LiC{sub 2}B{sub 9}H{sub 10}){sub 2}]. Reaction of [Co(LiC{sub 2}B{sub 9}H{sub 10}){sub 2}] with ethylene oxide followed by protonation of the alcohol group with IIcl (g) gives the dialcohol monomer, [Co{sub 13}(C{sub 2}B{sub 9}H{sub 10}){sub 2}(C{sub 2}H{sub 4}OH){sub 2}]. The dialcohol monomer has been characterized by FTIR, and {sup 1}H and {sup 13}C NMR. The characterization as well as the reaction chemistry of the dialcohol monomer with isocyanates will be discussed.
