He, Xinxin; Wang, Xinyan; Tse, Ying-Lung Steve; Ke, Zhihai; Yeung, Ying-Yeung published their research in ACS Catalysis in 2021. The article was titled 《Bis-selenonium Cations as Bidentate Chalcogen Bond Donors in Catalysis》.Quality Control of 5-Bromobenzo[d][1,3]dioxole The article contains the following contents:
Hydrolytically stable bidentate Lewis acid catalysts derived from selenonium dicationic centers were developed. The bis-selenonium catalysts were employed in the activation of imine and carbonyl groups in various transformations with good yields and selectivity. Lewis acidity of the bis-selenonium salts was found to be stronger than that of the monoselenonium systems, attributed to the synergistic effect of the two cationic selenonium centers. In addition, the bis-selenonium catalysts were not inhibited by strong bases or moisture. In addition to this study using 5-Bromobenzo[d][1,3]dioxole, there are many other studies that have used 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4Quality Control of 5-Bromobenzo[d][1,3]dioxole) was used in this study.
Furthermore, the coupling of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4) with β-methallyl alcohol was catalyzed by Pd(OAc)2 in combination with P(t-Bu)3.Quality Control of 5-Bromobenzo[d][1,3]dioxole
