Isolation of a Cationic Platinum(II) s-Silane Complex
The platinum complex [Pt(ItBuiPr′)(ItBuiPr)][BArF] interacts with tertiary silanes to form stable (<0 °C) mononuclear PtII σ‐SiH complexes [Pt(ItBuiPr′)(ItBuiPr)(η1‐HSiR3)][BArF]. These compounds have been fully characterized, including X‐ray diffraction methods,...
Epimerization of glucose over ionic liquid/ phosphomolybdate hybrids: structure-activity relationship
The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose was studied. A clear evidence of structure–activity relationship was found. The inorganic part of the...
Selective catalytic synthesis of amino-silanesat part-per million catalyst loadings
Platinum(II) complex [Pt(ItBu0)(ItBu)][BArF4] (1a) is a highly active and selective catalyst in the dehydrocoupling of amines and silanes at part-per-million catalyst loadings (up to 10 ppm, 0.001 mol%), achieving the highest TON and TOF numbers reported in the...
Broad Scope Synthesis of Ester Precursors of Nonfunctionalized Chiral Alcohols Based on the Asymmetric Hydrogenation of α,β- Dialkyl-, α,β- Diaryl-, and α-Alkyl-β-aryl-vinyl Esters
The catalytic asymmetric hydrogenation of trisubstituted enol esters using Rh catalysts bearing chiral phosphinephosphite ligands (P-OP) has been studied. Substrates covered comprise α,β-dialkyl, α-alkyl-β-aryl, and α,β-diarylvinyl esters, the corresponding...
Glycodendrimers as chondroitin sulfate mimetics: synthesis and binding to growth factor midkine
Chondroitin sulfate (CS) is a member of the glycosaminoglycan (GAG) family, a class of polysaccharides implicated in relevant biological functions. The structural complexity of these carbohydrates demands the development of simple glycomimetics as useful tools to...
