Functionalized cobalt bis(dicarbollide) ions as selective extraction reagents for removal of M2+ and M3+ cations from nuclear waste, crystal and molecular structures of the [8,8 '-mu-CIP(O)(O)(2)(1,2-C2B9H10)(2)-3,3 '-Co]HN(C2H5)(3) and [8,8 '-mu-Et2NP(O
Original language description
New reliable synthetic methods leading to derivatives of the closo-[(1,2-C2B9H11)(2)-3,3'-Co](-) (1) anion 1 with phosphorus containing substituents on the cage boron atoms have been successfully developed, starting from its 8-OH (2) and 8,8'-(OH)(2) (3)hydroxyderivatives. Reactions of 2 with either Cl3PO or PhCl2PO followed by hydrolysis gave 8-(HO)(2)PO-O- (4) and [(8-PhPO(OH) -O)- 1,2-C2B9H10)(1,2-C2B9H11)-3,3'-Co](-) (5) phosphorylated species, respectively. Analogous reactions Of Cl3PO with 3 provided a chlorine bearing bridged product [8,8'-mu-ClP(O)(O)(2) < (1,2-C2B9H10)(2)-3,3'-Co](-) (6) with surprisingly high hydrolytic stability. The anticipated anion [8,8'-mu-(HO)(O)-P(O)(2) < (1,2-C2B9H10)(2)-3,3'-Co](-) (7) with phosphoric acid as the bridging substituent was obtained after alkaline hydrolysis of compound 6. The related [8,8'-mu-Ph(O)P(O)(2) < (1,2-C2B9H10)(2)-3,3'-Co](-) (8) derivative was prepared by similar reaction of 3 with PhCl2PO and subsequent hydrolysis. Further
