Nanoporous aluminosilicate mediated transacetalization reactions: Application in glycerol valorization

Nanoporous silicate materials, produced using an evaporation-induced self-assembly (EISA) approach, are highly effective catalysts for transacetalization reactions. Both acyclic acetals and ketals undergo rapid exchange in the presence of low loadings of nanoporous aluminosilicate materials and diols and triols to generate the corresponding cyclic acetals and ketals in excellent yield. The protocol is rapid, employs mild conditions, and the catalyst can be recycled a number of times without loss of activity.
