Two chiral manganese(III) salen complexes were immobilized onto functionalized porous clay heterostructures (PCHs). The Jacobsen complex was anchored onto the PCH derivatized with phenoxyl groups (CAT_1) by axial coordination between the metal center and the support. The manganese(III) salen complex containing vinyl functionalities was grafted onto the mercapto-derivatized PCH through the ligand (CAT_2)...
Saponites containing divalent Mg, Ni, or Fe as octahedral cations and trivalent Al and Fe substituting Si in the tetrahedral sheet were synthesized using microwave radiation. Saponite with a high specific surface area was obtained in all the syntheses, although Fe-Al saponite crystallized was impurified by Fe 2 O 3 and analcime. The catalytic activity of the solids for the epoxidation...
