Abstract
Abstract
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) & Melting points .
