Abstract:
تضمنت هذة الدراسة تحضير مركبات مختلفة لل 5,4 - ثنائي فنيل ايميدازول من خلال خطوات كثيرة : شملت الخطوه الاولى من البحث تحضير مركب الازو ايميدازول (H) وذلك عن طريق تفاعل الازدواج لل 5,4 - ثنائي فنيل ايميدازول مع املاح الديازونيوم 4 - امينو اسيتوفينون.اما ا | This study deals with the synthesis of new different compounds of 4,5 - di phenyl imidazole via many steps : The first part of this study includes synthesis of azo compounds of 4,5 - di phenyl imidazole by coupling reaction of 4,5 - di phenyl imidazole with Diazonium salts then of 4 - aminoacetophenone. The second part includes synthesis of new azo - chalcone derivatives (H1 - H4)by react on(H) coumpound with different derivatives of benzaldehyde.The third part includes the synthesis of oxazine compounds (H5 - H7) by reaction of (H1,H2,H3)respectively compounds with urea.The fourth part includes synthesis of Schiff base(H8 - H13) by the reaction of the compound(H) with different derivatives of aniline.The fifth part of includes synthesis of oxazepine derivatives(H14 - H21) from reaction of Schiff bases (H8 - H13)with phthalic anhydride and (H9,H10)with maleic anhydride,and synthesis of titrazoles derivatives (H22)from reaction of Schiff base(H12) with Sodium azid (NaN3).The final part of this research includes the biological activity study of some prepared compounds and showes that there is inhibitory activity against fungul.The chemical reaction are checked by using (T.L.C) Technique, all the prepared compounds were characterized by using FT - IR and (¹H - NMR) and (C.H.N) for some of these compounds , and these identification studies approved the correctness of structures for the prepared derivatives.The following schemes explains the stages of reactions for the prepared compounds
