- Remote sp2C-H Carboxylation via Catalytic 1,4-Ni Migration with CO2
-
A remote catalytic reductive sp2 C-H carboxylation of arenes with CO2 (1 bar) via 1,4-Ni migration is disclosed. This protocol constitutes the first catalytic 1,4-Ni migration reported to date, thus offering new vistas in the Ni-catalyzed reductive coupling arena while providing an unconventional new platform for incorporating electrophilic sites at remote sp2 C-H linkages.

- Design, synthesis and biological evaluation of benzimidazole-pyridine-piperidine hybrids as a new class of potent antimicrobial agents
-
A series of novel benzimidazole-pyridine-piperidine hybrids was synthesized in good yields and characterized by spectral and elemental analyses. The compounds 4a-h and 5a-c were evaluated for their in vitro antibacterial activity against gram-positive org

- 4,4′-Bis(trifluoromethyl)-2,2′-bipyridine-a multipurpose ligand scaffold for lanthanoid-based luminescence/19F NMR probes
-
The tetradentate ligand 4,4′-bis(trifluoromethyl)-2,2′- bipyridine-6,6′-dicarboxylic acid (H21) and three corresponding anionic rare earth complexes [RE(1)2]- (RE = Y, Tb, Dy) were synthesized. The terbium and dysprosium complexes show lanthanoid-centered luminescence in aqueous solution, as well as paramagnetically enhanced longitudinal magnetic relaxation of the 19F nuclei.
