One aspect of this project will aim to establish ynamides as effective substrates for sydnone cycloaddition reactions
. Ynamides are easily prepared in a single step and are stable, and easy to use.

are one of the most important synthetic processes, with both synthetic and mechanistic interest in organic chemistry.
Then the compound 12 was subjected to 1,3-dipolar cycloaddition reaction
with the oxime 7a in the presence of NCS/NaHC[O.sub.3] in ethyl acetate as solvent to give very low yield of the compound 17a (Scheme 2).
During cycloaddition reaction
, chalcone moiety was also brominated.
In this study, we report a method to introduce abundant nitrile groups to pristine graphene by cycloaddition reaction
of graphene with tetracyanoethylene oxide [18-20] (TCNEO) Scheme 1).
His design employs either polyesters (more sustainable due to access to bio-based raw materials) or poly-imides (for high-temperature applications) that are functionalized with cyclobutane substrates through the photochemistry of maleic anhydrides, which undergo a [2[Plus]2] cycloaddition reaction
to form cyclobutanes when exposed to one wavelength of light and the reverse when exposed to another.
We investigated the incorporation of water soluble Lewis acids that promote a 1, 3-dipolar cycloaddition reaction
between organic molecules in water.

These polymers have gained a huge interest academically in recent years as the azide group can undergo a cycloaddition reaction
with a terminal alkyne group in presence of a Cu(I) catalyst to make block, graft, brush, and star polymers.
Philip Dawson, a member of Faculty of 1000 Biology and leading authority in chemistry and cell biology, reviewed a study and observed that the novel cycloaddition reaction
is fast, very specific, and requires minimal manipulation of the cells.
