Regiospecific synthesis by copper- and ruthenium-catalyzed

Reduced graphene oxide (RGO) has been covalently functionalized with porphyrin moieties by two methods: A straightforward Prato reaction (i.e. a 1,3-dipolar cycloaddition) with sarcosine and a formyl-containing porphyrin, and a stepwise method that involves a 1,3-dipolar cycloaddition to the RGO surface using 4-hydroxybenzaldehyde, followed by nucleophilic substitution with an appropriate

Synthetic Applications of 13-Dipolar Cycloaddition

Copper(I)-catalyzed 1,3-dipolar cycloaddition reaction of nonfluorescent 3-azidocoumarins and terminal alkynes afforded intense fluorescent 1,2,3-triazole products. The mild condition of this reaction allowed us to construct a large library of pure fluorescent coumarin dyes. Since both azide and alkyne are quite inert to biological systems

13-dipolar cycloadditions of trimethylsilyldiazomethane

Due to the large variety of 1,3-dipoles as well as dipolarophiles, the 1,3-dipolar cycloaddition is a very excellent reaction for the synthesis of various five-membered heterocyclic rings. Also, owing to their high stereo- and regioselectivity, these cycloaddition reactions are useful in organic synthesis [ 2 , 3 ].

seasons in the philippines pdf

The Seasons of Weather in the Philippines – Either Dry or Rainy. We all know there are four seasons of weather (spring, summer, winter and fall), right? In tropical countries like the Philippines, the four seasons aren’t even recognized. Officially or unofficially, it really doesn’t matter. What matters is what the people living in the Philippines recognize. The one thing that bothers me
