Synthesis, spectral characterization and antioxidant activities of 2′, 6′-diphenyl-1, 3- dihydrospiro [benzo[d] imidazole-2,4′-piperidine]

Elanchezhian Balachandravinayagam*, Manivannan Natarajan and Selvanathan Ganesan Department of Chemistry, A.V.C. College (Autonomous), Mannampandal, Mayiladuthurai, Tamilnadu, India-609305 Abstract 2′,6′-diphenyl-1,3-dihydrospiro[benzo [d] imidazole-2,4′-piperidine] was synthesized by condensing  2,6-diarylpiperidin-4-one with o-phenylene diamine. The synthesized compound was characterized by IR, Mass and NMR spectral studies. NMR spectral assignments are made unambiguously by their one-dimensional (1H and 13C NMR) and two-dimensional (1H–1H COSY and NOESY) NMR ... Read More »
