He, Xinxin published the artcileBis-selenonium Cations as Bidentate Chalcogen Bond Donors in Catalysis, Safety of 2-Methoxynaphthalene, the publication is ACS Catalysis (2021), 11(20), 12632-12642, database is CAplus.
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.
ACS Catalysis published new progress about 93-04-9. 93-04-9 belongs to ethers-buliding-blocks, auxiliary class Naphthalene,Ether, name is 2-Methoxynaphthalene, and the molecular formula is C11H10O, Safety of 2-Methoxynaphthalene.
