Liu, Yong-Liang; Wang, Xiao-Ping; Li, Ya published an article in 2022. The article was titled 《Lewis Base-catalyzed β-Addition of (Arylsulfonyl) fluoromethane Derivatives to Allenoates》, and you may find the article in ChemistrySelect.Quality Control of Benzyl 2-bromoacetate The information in the text is summarized as follows:
A highly selective TMG-catalyzed β-addition of (arylsulfonyl)fluoromethane derivatives to allenoates has been developed. Cyano, nitro, and ester-functionalized (arylsulfonyl)fluoromethanes were all suitable substrates, giving a series of structurally diverse β-addition products bearing a stereogenic fluorinated carbon center. A possible reaction pathway was also presented. After reading the article, we found that the author used Benzyl 2-bromoacetate(cas: 5437-45-6Quality Control of Benzyl 2-bromoacetate)
Benzyl 2-bromoacetate(cas: 5437-45-6) belongs to benzyl acetate. Benzyl acetate is a synthetic chemical produced for industry from benzyl alcohol and acetic acid, but is also naturally present in the essential oils of many plants, including jasmine and ylang ylang.Quality Control of Benzyl 2-bromoacetate
