Synthesis and characterization of novel quinoline selenium compounds: X-ray structure of 6-methoxy-3H-[1,2]diselenolo[3,4-b]quinoline

A series of novel and synthetically important quinoline selenium compounds have been successfully synthesized using an efficient and simple strategy. The method employed leads to the synthesis of both cyclic as well as open chain quinoline selenium compounds. The prepared selenium compounds have been characterized with the help of various spectroscopic techniques viz., NMR (¹H, ¹³C), FT-IR, mass spectrometry. The structure of 6-methoxy-3H-[1,2]diselenolo[3,4-b]quinoline has been determined by X-ray crystallography.
