Electric Literature of 20439-47-8, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 20439-47-8, name is (1R,2R)-Cyclohexane-1,2-diamine. In an article£¬Which mentioned a new discovery about 20439-47-8
Chiral manganese(III) salen catalysts immobilized on MCM-41 and delaminated zeolites ITQ-2 and ITQ-6 through new axial coordinating linkers
We report that the catalytic behavior and enantioselectivity of three different chiral Mn(III) salen complexes anchored to traditional supports such as MCM-41 (38-A pore diameter) and delaminated zeolitic materials ITQ-2 and ITQ-6 strongly depend on whether the complexes are attached to the surfaces through the chiral equatorial tetradentate salen ligand or via the apical ligand. As for the case of unsupported complexes, this experimental observation has been accounted for strong variations in the conformational preference of the catalyst intermediate toward the approaching olefin, as well as to unfavorable structural changes in the complex. In addition, control of the hydrophobicity of the surface allows for optimization of selectivity in obtaining chiral epoxides.
