- Theoretical evaluation on solubility of synthesized task specific ionic liquids in water
-
Task specific ionic liquids (TSILs) are synthesized and utilized for extraction of different metal atoms from their complexes. Since physico-chemical properties of ionic liquids (ILs) are modified by water (H2O) molecules, less hydrophilic ILs

- Histidine and deuterium labelled histidine by asymmetric catalytic reduction with gaseous H2 or D2; the role of strong non-coordinating acids
-
An efficient and convenient route for the preparation of natural and unnatural histidine by asymmetric hydrogenation with rhodium-phosphine complexes is described. The reductions were performed in the presence of HBF4 to generate an essential imidazolyl cation. Stereoselective incorporation of D2 in the α,β-positions was obtained by catalytic deuteration in the presence of MeOD.
