In 2019,Polymer included an article by Allegrezza, Michael L.; Thompson, Adam M.; Kloster, Alex J.; Konkolewicz, Dominik. SDS of cas: 94928-86-6. The article was titled 《Efficient coupling by oxygen accelerated photocatalyzed thiol-alkyne chemistry》. The information in the text is summarized as follows:
Thiol reactions have gained attention in many areas of chem. research, such as organic small mol. synthesis, polymer synthesis, and bimol. coupling due to the “”click”” chem. characteristics of this process. This work is a study of a novel method of photochem. thiol-alkyne reactions using alkyl halides and an Ir(ppy)3 photocatalyst. This process is shown to lead to rapid reactions and has the benefit of low catalyst and initiator concentrations relative to reagents. Remarkably, this reaction also has an unusual feature of an increased rate in the presence of oxygen, in contrast to many other types of radical processes. Catalyst and initiator concentrations and reaction conditions are varied in order to gain an understanding of the mechanism of this process. This chem. is then applied to the synthesis of hyperbranched polymers and polymer networks to demonstrate potential applications. In the experiment, the researchers used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6SDS of cas: 94928-86-6)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. SDS of cas: 94928-86-6
