Kannan, S.; Gamare, J. S.; Chetty, K. V.; Drew, M. G. B. published the artcile< Coordination and extraction studies of an unexplored bi-functional ligand, carbamoyl methyl pyrazole (CMPz) with uranium(VI), lanthanum(III) and cerium(III) nitrates>, Synthetic Route of 5326-82-9, the main research area is rare earth pyrazoleacetamide preparation structure; crystal structure uranium cerium pyrazoleacetamide nitrato; extraction uranium plutonium octylpyrazoleacetamide ligand; pyrazoleacetamide preparation uranium cerium lanthanum complexation; thermal decomposition uranyl pyrazoleacetamide complex.
The bi-functional carbamoyl Me pyrazole ligands, C5H7N2CH2CONBu2 (L1), C5H7N2CH2CONiBu2 (L2), C3H3N2CH2CONBu2 (L3), C3H3N2CH2CONiBu2 (L4) and C5H7N2CH2CON(C8H17)2 (L5) were synthesized and characterized by spectroscopic and elemental anal. methods. The selected coordination chem. of L1 to L4 with [UO2(NO3)2·6H2O], [La(NO3)3·6H2O] and [Ce(NO3)3·6H2O] was evaluated. Structures for [UO2(NO3)2 C5H7N2CH2CONBu2] (6) [UO2(NO3)2 C5H7N2CH2CONiBu2] (7) and [Ce(NO3)3{C3H3N2CH2CONiBu2}2] (11) were determined by single crystal x-ray diffraction methods. Preliminary extraction studies of the ligand L5 with U(VI) and Pu(IV) in tracer level showed an appreciable extraction for U(VI) and Pu(IV) up to 10 M HNO3 but not for Am(III). Thermal studies of 6 and 7 in air revealed that the ligands can be destroyed completely on incineration.
Polyhedron published new progress about Crystal structure. 5326-82-9 belongs to class amides-buliding-blocks, and the molecular formula is C10H20ClNO, Synthetic Route of 5326-82-9.
