Application of a novel nano-immobilization of ionic liquid on an MCM-41 system for trimethylsilylation of alcohols and phenols with hexamethyldisilazane

Synthesis and characterization of indium and thallium immobilized on isonicotinamide‐functionalized mesoporous MCM‐41: Two novel and highly active heterogeneous catalysts for selective oxidation of sulfides and thiols to their corresponding sulfoxides and disulfides

“…Such hybrid nanocomposites can incorporate some beneficial features of both organic and inorganic components into the mesoporous support with reactive and mechanical properties that are different from either of the completely organic or inorganic species. The strong covalent bonds thus increase the lifetime of the catalyst, the performance of these inorganic–organic hybrid materials is improved and the leaching of catalytically active sites can be avoided . Various indium and thallium compounds can promote a number of reactions such as C&bond;C bond formations, n ‐ tert ‐butoxycarbonylation of amines, acylation of alcohols, phenols and thiols, geminal diacylation of aldehydes and Suzuki cross coupling .…”

“…Thiocyanation of organic compounds [51] catalytically active sites can be avoided. [12][13][14][15][16][17][18][19][20] Various indium and thallium compounds can promote a number of reactions such as C&bond;C bond formations, [21] n-tert-butoxycarbonylation of amines, [22] acylation of alcohols, phenols and thiols, geminal diacylation of aldehydes [23] and Suzuki cross coupling. [24] Indium is often selected as the metal centre due to its low toxicity and high chemoselectivity.…”
