Abstract
Since the idea of a sustainable chemistry became an urgency for the scientific community, an exponential increasing in the use of heterogeneous recoverable catalysts was registered. Mesoporous silica (MCM) have played a prominent role as inert supporting materials in this field, because of their high specific surface areas, their large pore size and their thermal and chemical stability.[1] The efficiency of non toxic Er(III) salts as Lewis acid catalysts in homogeneous phase was largely explored by our group. This work is focused on the realization and application of a new class of heterogeneous catalysts based on the Er(III) chemistry. The MW-assisted synthesis and characterization, the rationalization of the MW–effect on the system, the application of a new MCM-Er(III) catalyst under non-conventional synthetic methods as US, MW and continuous-flow conditions will be presented.[2]I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
