Electric Literature of C20H14N4 And the article was included in ChemSusChem on April 22 ,2022. The article conveys some information:
A pyridinium-based complex with environment-friendly and earth-abundant ZnII ion was synthesized and explored as a green catalyst applied in activating mol. oxygen for the simple and efficient photooxidation of alcs. into aldehydes under additive-free and mild conditions. The metal coordination was conducive to promoting the electron transfer efficiency and introducing the heavy-atom effect for the increased generation of ·O2- and 1O2. Accordingly, improved photocatalytic performance of this complex compared to its precursor, no matter activity or selectivity, was obtained, facilitating the transformation of alcs. into aldehydes in a sustainable way. After reading the article, we found that the author used 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Electric Literature of C20H14N4)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. Electric Literature of C20H14N4
