Summery
In this study has been prepared of compound ( 1 ) ( 2- ( 4- (dimethylamino) benzylidene ) hydrazine -1-carboxamide ) by the reaction between ( 4- (dimethylamino) benzaldehyde ) and semicarbazide , Then formation the compound ( 2 ) (( 5 - ( 4-dimethylamino ) phenyl ) 1,3,4- oxadiazol -2- amine ) followed by I2 - mediated oxidative (C-O) bond , Schiff bases ( 3-5 ) have been produced by the condensation of compound (2) and the benzaldehyde dervatives ( 4- chloro benzaldehyde , 2- nitro benzaldehyde , 2,4- dimethoxy benzaldehyde ) , and Finally , the new compounds oxazepine , benzoxazepine , oxazepane ( 6-14 ) prepared by the reaction of anhydride ( phathalic , maleic , succinic ) with Schiff bases
The synthesized compound are identified by physical ( melting points , color change ) and spectral method such as ( IR , Proton - NMR)
