Forster, Dan; Guo, Weisi; Wang, Qian; Zhu, Jieping published their research in ACS Catalysis in 2021. The article was titled 《Photoredox Catalytic Three-Component Amidoazidation of 1,3-Dienes》.HPLC of Formula: 1530-32-1 The article contains the following contents:
Herein a three-component 1,2-amidoazidation of 1,3-dienes was reported. In the presence of fac-Ir(ppy)3 under blue LED irradiation, reaction of 1-aryl substituted 1,3-dienes with N-amidopyridinium salt and trimethylsilyl azide (TMSN3) affords exclusively the 1,2-amidoazidation products. The 1-alkyl substituted counterparts undergo the same reaction with moderate to high 1,2- vs 1,4-selectivity. Reduction of this mixture with PPh3 under dynamic kinetic conditions enriches significantly one of the two isomers thanks to the facile 1,3-azide shift (Winstein rearrangement) of the allyl azides. The results came from multiple reactions, including the reaction of Ethyltriphenylphosphonium bromide(cas: 1530-32-1HPLC of Formula: 1530-32-1)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.HPLC of Formula: 1530-32-1
