صنعت مركبات أيمينية بتفاعل مركبات ثنائية الكربونيل تير فتال ثناي ألدهيد و 2.2 -ثنائي متيل بروبال وأسيتيل أسيتون مع أمينات مختلفة. وصفت الايمينات المحضرة بتقانة التحليل العنصري و مطيافية ماتحت الأحمر و مطيافية الرنين النووي المغناطيسي للبروتون والكربونون 13.
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.

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).
This work represent synthesis of new benzoxazines polymers based on
either phenol or hydroquinone as a phenolic compounds and para
aminophenol as primary amine and paraformaldehyde.
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.
In this work, several samples of poly(propylene itaconat ortho
phthalate) based on itaconic acid and 1,2-propylene glycol were
prepared by polycondensation.
In this work, three new compounds of benzoxazine monomers were
synthesized based on (phenol, hydroquinone, 2-naphthol) and
triethoxysilyl propyl amine (TESPA) and paraformaldehyde. (TESPA)
were used to study its effect on the thermal stability of
polybenzoxazine
resulting from the ring opening polymerization of prepared monomers.
