Oxidative self-coupling of amines and cross-coupling with alcs. are important reactions for the synthesis of imines; however, catalytic systems for these reactions usually require expensive oxidant, complicated catalyst preparation, complex reaction set-up, and/or additives such as bases or cocatalysts. Here, authors report that amorphous cerium-manganese (Ce-Mn) oxides with hierarchical microsphere structure prepared by a facile method could exhibit excellent catalytic performance for the synthesis of various imines using air as the green oxidant under mild conditions. The Ce-Mn oxide heterogeneous catalysts could also be easily recovered and efficiently recycled without significant loss of activities. The excellent activities and the reusability of the Ce-Mn oxide microspheres offer potential advances in the synthesis of imine. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Safety of (4-Methoxyphenyl)methanol).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Safety of (4-Methoxyphenyl)methanol
