In the Organic Chemistry division, students Amal Mohamadi, Roqaya al-Awabdeh, Sara Yousuf and Suzan Ahmed presented their research work titled 'Catalytic epoxidation of olefins over transition metal ferrite nanoparticles', 'Catalytic oxidation of aldehydes over transition metal oxide nanoparticles', 'Extraction of triterpenoid saponins from Tetraena qatarense (zygophyllum qatarense) and their biological activities' and 'Synthesis of substituted 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles by cycloaddition
of substituted 3-amino-2-ene nitriles with 3-acetylcoumarin'.
The classical synthesis of these compounds involves cycloaddition
of monochloroacetyl chloride with imines (Schiff base) resulting in formation of 2-azetidinone .

reaction of fluoroketene with imines: Substituent effects.
The Cu-catalyzed Huisgen azide-alkyne 1, 3-dipolar cycloaddition
as a leading example of the click chemistry, because of its quantitative yields, mild reaction condition and tolerance of a wide range of functional groups.
The first step in this synthesis is the 2+3 cycloaddition
of 1,1-dibromoformaldoxime across the alkene of an allyl acetate.
Azomethine imine molecules possess a polar 1,3-dipole [N.sup.-]-[N.sup.+]=C fragment, which makes these compounds to be valuable precursors in the combinatorial chemistry of heterocycles prepared by cycloaddition

Reactions," The Journal of Physical Chemistry A, vol.
used dimethyl sulfoxide to weaken the B-N bonds through cycloaddition
, which make the part of B-N bonds on the surface of BNNTs hydrolysis and stripping the stripping BN molecular layer will be embedded in the BNNTs to form Y loop structure BNNTs .
