In 2019,Chemical Science included an article by Nguyen, Julia; Chong, Andrea; Lalic, Gojko. SDS of cas: 1779-49-3. The article was titled 《Nickel-catalyzed anti-Markovnikov hydroarylation of alkenes》. The information in the text is summarized as follows:
We have developed a nickel-catalyzed hydroarylation of alkenes using aryl halides as coupling partners. Excellent anti-Markovnikov selectivity is achieved with aryl-substituted alkenes and enol ethers. We also show that hydroarylation occurs with alkyl substituted alkenes to yield linear products. Preliminary examination of the reaction mechanism suggests irreversible hydrometallation as the selectivity determining step of the hydroarylation. After reading the article, we found that the author used Methyltriphenylphosphonium bromide(cas: 1779-49-3SDS of cas: 1779-49-3)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is used for methylenation through the Wittig reaction. It is utilized in the synthesis of an enyne and 9-isopropenyl -phenanthrene by using sodium amide as reagent. SDS of cas: 1779-49-3
