TL;DR: In this article, a solid peroxyacid based on organically modified silica has been developed for the epoxidation of alkenes, which has been successfully applied to a variety of applications.
45 citations
TL;DR: In this article, the use of zeolites as catalysts in organic rearrangements of interest in the synthesis of fine chemicals is discussed, such as the rearrangement of epoxides and α,β-epoxy ketones, the Claisen rearranging of allyl aryl ethers and an intramolecular hydroxyalkylation of an aromatic with an epoxide.
Abstract: Results are presented on the use of zeolites as catalysts in organic rearrangements of interest in the synthesis of fine chemicals viz., the rearrangement of epoxides and α,β-epoxy ketones, the Claisen rearrangement of allyl aryl ethers and an intramolecular hydroxyalkylation of an aromatic with an epoxide.

TL;DR: In this article, a multifunctional probe for testing the outer surface activity of zeolites was developed, and its use is demonstrated by the hydrogenation of the double bond over platinum/H-BEA, in which comparison with various non zeolite-based platinum catalysts enabled the proportion of platinum clusters located on the outer surfaces to be quantified.
26 citations
TL;DR: In this article, various cyclic α,β-epoxy ketones were rearranged to α-formyl ketones and/or vic-diones in the presence of catalytic amounts of zeolites and montmorillonite K10.

TL;DR: In this paper, an overview is given on the last development of catalytic methods for the preparation of substituted furans from carbohydrates and ensuing polymers, and a short examination on what could be the future of furan chemistry with the recent development of ionic liquids as solvents.
Abstract: In this review, an overview is given on the last development of catalytic methods for the preparation of substituted furans from carbohydrates and ensuing polymers. The review starts with the recent aspects in the synthesis of some key furan monomers in the presence of solid catalysts. In the second part, selected examples are given of polymerization systems leading to furan-based materials with promising properties, thus constituting a serious alternative to petroleum-based counterparts. Finally, a short examination is given on what could be the future of furan chemistry with the recent development of ionic liquids as solvents.

TL;DR: In this article, various approaches towards the immobilization of molecular homogeneous catalysts are introduced, focusing on catalysts where an organic molecule is attached to the surface of an inorganic support material via a covalent bond forming the so-called hybrid organic-inorganic catalysts.
Abstract: Various approaches towards the immobilization of molecular homogeneous catalysts are introduced, focusing on catalysts where an organic molecule is attached to the surface of an inorganic support material via a covalent bond forming the so-called hybrid organic–inorganic catalysts. The application of this new class of catalysts in a wide variety of organic reactions is reviewed.
