Synthesis of Various –Membered Rings from (aze-cycles)

Series compounds containing heterocyclic compounds (various membered ring) and formazane have been synthesized in present work. Some of these compound used imine and amino compounds as starting materials in their synthesis like compounds [1–4] to prepare cycles. This work involved, synthesis of oxazepine compounds [9] as (seven– membered ring), which is used in synthesis of tri azeocine compounds [10] as (eight–membered ring), bi cyclic compounds [11], di azepine compounds [12,13], di azetidine–thione and di azrine as (four or (three–membered ring) linked. with di azepine (seven–ring) like compounds [13, 15], formazane (azo –imine) like compounds [6, 22]. The structure of these compounds were characterized by (H.NMR, FT.IR, C.H.N) –Techniques and their melting points.
