Novel biphenyl organocatalysts for iminium ion-catalyzed asymmetric epoxidation
摘要:
Two novel chiral biphenyl iminium salts derived from L-acetonamine, containing electron-withdrawing 3,3'-substituents on the biphenyl unit, have been prepared and tested as asymmetric catalysts for epoxidation of prochiral alkenes. The results are compared with those achieved using the corresponding unsubstituted system. (c) 2012 Elsevier Ltd. All rights reserved.

In this work, a series of metal–organic framework (MOF)‐derived CoPd nanoalloys have been prepared. The nanocatalysts exhibited excellent activities in the hydrogenation of nitroarenes and alkenes in green solvent (ethanol/water) undermildconditions (H2 balloon, room temperature). Using ZIF‐67 as template for both carbon matrix and cobalt precursor coating with a mesoporous SiO2 layer, the catalyst
