A hydrophilic ligand that contains only C, H, O, and N substituents and uses a 6,6′-bis(1 H -1,2,3-triazol-4-yl)-2,2′-bipyridine (BTzBP) structural core has been synthesized. The effect of adding water-soluble groups onto extractant ligands has been extensively studied to facilitate the efficient partitioning of 4f and transuranic 5f elements for the treatment of spent nuclear fuel. Soft, N-donor ligands exhibit greater binding affinities for the trivalent actinides over the trivalent lanthanides, making BTzBP ligands an ideal candidate in the search for extractants to be used on an industrial scale. To date, hydrophobic BTzBPs have been shown to exhibit physical and chemical properties that might be conducive to nuclear waste processing conditions. However, hydrophilic BTzBPs have yet to be reported. Herein, we show the synthesis of a hydrophilic BTzBP ligand featuring cationic water solubilizing groups attached to the bipyridal rings.

Preparation method of 1-subtituted-1H-1,2,3-triazole-4-carboxylic acid
-
Paragraph 0041; 0042; 0043, (2016/10/09)
The invention provides a preparation method of 1-subtituted-1H-1,2,3-triazole-4-carboxylic acid. The preparation method includes the following steps: 1-substituted-4,5-dibromo-1H-1,2,3-triazole is added to an isopropylmagnesium chloride, such that 1-substituted-4-bromo-1H-1,2,3-triazole is obtained through a reaction; an isopropylmagnesium chloride-lithium chloride complex is added directly, such that a mixture of 1-substituted-1H-1,2,3-triazole-4-carboxylic acid and 1-substituted-4-bromo-1H-1,2,3-triazole-5-carboxylic acid is obtained; a base and iodomethane are added to the mixture, such that methyl 1-substituted-4-bromo-1H-1,2,3-triazole-5-carboxylare is obtained through a reaction; the aqueous layer is adjusted with hydrochloric acid until a pH value is 1-5; extraction is carried out with an organic solvent, and drying and concentration crystallization are carried out, such that 1-substituted-1H-1,2,3-triazole-4-carboxylic acid is obtained. The method is suitable for industrial production, and has a great application value.

scheme or table, p. 4632 - 4635 (2010/12/18)
The regioselective N-alkylation of 1,2,3-triazoles 1 - 6 was studied. Good to excellent N-2 selectivity and high chemical yields for N-2-substituted 4,5-dibromotriazoles 7 were obtained with 4,5-dibromo- and 4-bromo-5- trimethylsilyl-1,2,3-triazoles. These building blocks can be readily converted to 2-mono-, 2,4-di-, and 2,4,5-polysubstituted triazoles 10 - 15, providing a general, protective, group-free method for the synthesis of N-2-substituted triazoles. Observed regioselectivities can be rationalized by a combination of Frontier Molecular Orbital, steric, and electrostatic directing effects on the heterocyclic scaffolds.

Towards the total synthesis of cyclo[n] carbons and the generation of cyclo[6]carbon

, p. 1535 - 1543 (2007/10/03)
We describe efforts towards the synthesis of some allotropes of carbon, the cyclo[n]carbons where n = 18, 24 and 30. The key intermediate 11 is hexa-1,3,5-triyne with the central triple bond masked as a 1-amino-1,2,3-triazole derivative. Cyclo-oligomerisation of this by oxidative coupling gives macrocyclic precursors of C18, C24 and C30. C30 is a proposed intermediate in the formation of C60 and we also describe some attempts at the synthesis of C60 via the chemical generation of benzotriyne, cyclo[6]carbon.
