Mandal, Tanumoy; Azim, Aznur; Das, Sanju; De Sarkar, Suman published an article in 2022. The article was titled 《Organophotoredox Catalyzed Stereoselective Nitration of Olefins with tert-Butyl Nitrite under Air》, and you may find the article in Asian Journal of Organic Chemistry.Application In Synthesis of Ethyltriphenylphosphonium bromide The information in the text is summarized as follows:
An efficient method for the E-selective synthesis of nitroolefins was developed by employing DDQ as the organophotoredox catalyst in combination with tert-BuONO (TBN) as a nitrating agent under visible-light irradiation This green transition metal-free approach utilizes aerial oxygen as the terminal oxidant and occurs at room temperature Following the established protocol, 41 different olefines containing broad diversity of substituents were nitrated in good to excellent yields. Mechanistic experiments and photophys. studies revealed the probable mechanism. In the experiment, the researchers used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Application In Synthesis of Ethyltriphenylphosphonium bromide)
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.Application In Synthesis of Ethyltriphenylphosphonium bromide
