Synthesis, Spectral Characterization and Ligation of N-(2-(Phenylseleno)ethyl)phthalimide

Abstract

PhSe-Na+ generated in situ by reduction of PhSeSePh, with sodium borohydride on reaction with N-(2-bromoethyl) phthalimide in N2 atmosphere results in the formation of N-[2-(phenylseleno)ethyl]phthalimide (L1). The title compound has been characterized by elemental analysis, FT-IR, 1H and 13C NMR techniques. The crystal structure of L1 has been solved by direct methods and refined by full-matrix least squares. The ligand L1 crystallize in the monoclinic space group. Selenium forms two Se-C linkages, one is due to Se-Calkyl and the other one to Se-Caryl. Further, the ligation reaction of L1 with complex 1 is also explored whose identities are characterized by spectroscopic techniques.
