Abstract AR
في هذه الدراسة تم تحضیر3- اسیتایل الكومارین (1) من مفاعلة السالسیلدیهاید مع اسیتواسیتات الاثیل بوجود الببریدین.
ثم مفاعلة الناتج (1) مع البروم بوجود الكلوروفورم لینتج 3- (2-برومو اسیتایل كومارین) (2).
مركب (3) یحضر بمفاعلة المركب (2) مع الایمیدازول لینتج المركب (3) الذي تفاعله مع الهیدرازین هیدریت و الفنیل هیدرازین و4 -2- ثنائي نایترو فنیل هیدرازین لینتج المركبات (4و 5 و6) على التوالي.
ثم مفاعلة المركب(3) مع مختلف الأمينات الاروماتیة و الالیفاتیة لینتج المركبات (15 -7).
شخصت المركبات الناتجة بواسطة الطرائق الفیزیاویة و التحلیلات الطیفیة المتوفرة(IR,U.V).
Abstract EN
3-acetyl coumarin (1) was prepared by reacting salicyldehyde with ethylacetoacetate.3-(2-bromoacetyl coumarin (2) was also prepared by reacting 3-acetyl coumarin with bromine in chloroform solution.
Reaction of compound (2) with imidazol in dioxan solution to gave 3-(1H-imidazol- 1yl-acetyl) coumarin(3).
Compounds (4,5,6) were synthesized by the reaction of compound (3) with hydrazine hydrate, phenyl hydrazine, 2,4- dinitro-phenylhydrazine respectively.
Compound (7-15) were synthesized by the reaction of compound (3) with various aromatic and aliphatic amines.
The structures of all the synthesized compounds have been established on the basis of physical, spectral (IR, U.V) data.
