Using of Intramolecular Condensation Reaction in Synthesis of Geterocyclics of (Se, S, N, O)-Atoms

In this paper, synthesis of five and seven-membered ring which containing hetroatom (Se, S, N, O) via several steps, the first step in this reaction, 2,2-methylene-bis(4-nitro phenol) reacts with (selenium, sulphur, nitrogen, oxygen)-compounds to yield cyclic derivatives of (Se, S, N,O) which cyclized via intramolecular condensation reaction in the second step. The formated compounds [1-9] have been investigated by using various chemical techniques, such as:(H-NMR-Spectra, (C.H.N)-analysis, FT.IR-spectra) and Melting points.
