Phase-Selective Catalysis in Emulsions Stabilized by Janus Silica- Nanoparticles

Metal-containing Janus particles are used as interfacial catalyst/emulsifiers that catalyze reactions in biphasic systems with controlled “phase selectivity”, that is, conversion of the desired reaction on one side of the emulsion. The reaction may affect the solubility of the molecule in one phase, causing migration to the opposite phase. As a result, combined reaction and separation can be ac...

Serial ligand catalysis: a highly selective allylic C-H oxidation.

We are reporting a mild, chemo-, and highly regioselective Pd(II)-catalyzed allylic oxidation of alpha-olefins to furnish branched allylic esters that proceeds via a novel serial ligand catalysis mechanism in which two different ligands (i.e., vinyl sulfoxide 2 and BQ) interact sequentially with the metal to promote distinct steps of the catalytic cycle (i.e., C-H cleavage and pi-allyl function...

Reactivity of the gold/water interface during selective oxidation catalysis.

The selective oxidation of alcohols in aqueous phase over supported metal catalysts is facilitated by high-pH conditions. We have studied the mechanism of ethanol and glycerol oxidation to acids over various supported gold and platinum catalysts. Labeling experiments with (18)O(2) and H(2)(18)O demonstrate that oxygen atoms originating from hydroxide ions instead of molecular oxygen are incorpo...

New Insights Into Amyloid Formation and Structure by Innovative Atomic Force Microscopy Methods

Aging of the world population has increased the visibility of neurodegenerative disorders, such as Parkinson’s and Huntington’s diseases. These human illnesses are strictly linked with the aggregation towards amyloid fibrillar structures of -synuclein and huntingtin proteins, respectively. The use of Atomic Force Microscopy is essential to unravel the characteristics of amyloid structures at t...

Oxidation Catalysis by Enzymes in Microemulsions

Microemulsions are regarded as “the ultimate enzyme microreactors” for liquid oxidations. Their structure, composed of water nanodroplets dispersed in a non-polar medium, provides several benefits for their use as media for enzymatic transformations. They have the ability to overcome the solubility limitations of hydrophobic substrates, enhance the enzymatic activity (superactivity phenomenon) ...
