These alkyne surrogates require significantly less Cu catalyst are the only alkyne reagents reported to date which enable chemoselective control in a sequential two-step CuAAC process.
Alkylated pyridine alkaloids, especially those having a long functionalized (NO2, NH2, NH2O, C=C, alkyne,) chain alkyl at C-3 of the pyridine ring, are abundantly isolated from marine sponges of the order Haplosclerida, which allowed us to consider 3alkyl pyridine compounds as chemotaxonomic markers for the systematic identification of haplosclerid members [6].
For the Health and Social Service sector, 'Integrase-Controlled Excision of Metal-Resistance Genomic Islands in Acinetobacter baumannii' by Dr Zaaima al Jabri won, while Muhammad S Khan won the Energy and Industry sector for his project 'Impact of the Alkyne Substitution Pattern and Metalation on the Photoisomerisation of Azobenzene-Based Platinum (II) Diynes and Polyynes'.
Each of these azide compounds was subject to reaction with fifty different alkyne moieties by using the CuAAC click chemistry approach.

It can generate pentabasic 1,3-oxazole which is an important compound in both synthetic chemistry [5] and biochemistry [6-9] through [3 + 2] ring addition reaction with alkyne. Considering the important significance of NCO free radical in combustion, biochemistry, synthetic chemistry, and interstellar chemistry, NCO has attracted wide research attention from chemists.
EdU, a thymidine analog in which a terminal alkyne group substitutes the methyl group in the 5th position, is incorporated into cellular DNA during DNA replication in proliferating cells [18].
The functional groups on the surface of biochar, such as hydroxyl, carboxyl, ether, amide, amine, alkayl, alkyne, alkine and carbonyl are responsible for adsorption of PTEs from wastewater.
The band at 2016 cm-1 is typically is attributed to alkyne group.
