The following imines: 1.8.13.20-tetraaza-13.3.6.18-diphenyl cyclotetracosan-
1.8.13.19- tetraene and butyradamantine, N.N’-di (admantyl) terephthimine
and 1.5.14.18-tetraaza-2.4.15.17-tetramethylcyclotetracosan-1.8.13.19- tetraene
based on dicarbonyl and amines were synthesized by reaction of dicarbonyl
compounds and different amines. The imines have been characterized by EA
(elemental analyses), IR, 1H- NMR and 13C-NMR.
The heterocyclization of unsaturated nitriles and ethyne catalyzed by
cyclopentadienyl - ١،٥ - cis, cis-cyclooctadiene-cobalt (I) and promoted by light
has been studied in toluene as solvent.
Acrylonitrile and substituted acrylonitriles gave satis
fying results
interesting for the preparation of ٢-vinylpyridines.
No reaction was observed using fumaronitrile, maleonitrile and
allycyanides.
(E)/(Z)-ratio of reactants and products seems not to be influenced within the
reaction.
تم في هذا البحث دراسة تفاعل أكسيد البنزوفيورازان مع الأسيتون لتشكيل المركب2-متيل 1 , 4-ثنائي أكسيد الكينوكسالين باستخدام الحفز الضوئي من خلال اتباع منهجية علمية جديدة تعتمد على محاكاة التفاعل كوانتياً ومن ثم تطبيقه تجريبياً
تم في هذا البحث تحضیر تسعة مركبات من مشتقات الإندول باستخدام تفاعلات متنوعة
مثل الأسیلة والتكاثف الألدولي وتشكیل أسس شیف "الإیمینات"،
Aseries of Schiff base and their derivative (fluorene) have been synthesized primary
amines was condensed with 2-acetyl fluorene in DMF (dimethyl formamide) in the
presence of conc. HCl acid as catalyst to yield the Schiff base (1). The Schiff base
(2,3)
and (4) were prepared from the reaction of Schiff base (1) with 2-hydroxy-5-methyl-1,3-
benzenedicarboxaldehyde and 2,5-dihydroxy benzaldehyde respectively. and The Schiff’s
base (4) was treated with monochloroacetyl choride to give 1- substituted-4(2-fluorenyl)-3-
chloro Azolidine-2-on (5).
