Reference of Ethyltriphenylphosphonium bromideIn 2021 ,《Electrochemical oxidative Z-selective C(sp2)-H chlorination of acrylamides》 appeared in Chemical Communications (Cambridge, United Kingdom). The author of the article were Harnedy, James; Hareram, Mishra Deepak; Tizzard, Graham J.; Coles, Simon J.; Morrill, Louis C.. The article conveys some information:
An electrochem. method for the oxidative Z-selective C(sp2)-H chlorination of acrylamides was developed. This catalyst and organic oxidant free method was applicable across various substituted tertiary acrylamides and provides access to a broad range of synthetically useful Z-β-chloroacrylamides in good yields (22 examples, 73% average yield). The orthogonal derivatization of the products was demonstrated through chemoselective transformations and the electrochem. process was performed on gram scale in flow. After reading the article, we found that the author used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Reference 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. CatOnium ETPB is also used as catalysts in the synthesis of certain organic compounds.Reference of Ethyltriphenylphosphonium bromide
