Superacid-Promoted Hydroxyalkylation of 1,2-Indandiones

Superacid promoted reactions of N-acyliminium salts and evidence for the involvement of superelectrophiles.

Experimental and theoretical studies suggest the involvement of dicationic, superelectrophilic N-acyliminium ions in conversions catalyzed by superacids.

Aromatic ionomers with superacid groups.

Aromatic polymers containing perfluorosulfonic acid groups show well-developed and interconnected ionic clusters, and thus high proton conductivity at wide humidity range.

Superacid Passivation of Crystalline Silicon Surfaces.

The reduction of parasitic recombination processes commonly occurring within the silicon crystal and at its surfaces is of primary importance in crystalline silicon devices, particularly in photovoltaics. Here we explore a simple, room temperature treatment, involving a nonaqueous solution of the superacid bis(trifluoromethane)sulfonimide, to temporarily deactivate recombination centers at the ...

Material and device properties of superacid-treated monolayer molybdenum disulfide

New domino radical synthesis of aminoalcohols promoted by TiCl4-Zn/t-BuOOH system: selective hydroxyalkylation of amines in alcohol or in cyclic ether cosolvents.

We report a new and fast domino synthesis of aminoalcohols under mild conditions. The free-radical reaction of aliphatic and aromatic amines with alcohol cosolvents is promoted by means of the TiCl(4)-Zn/t-BuOOH system. According to the proposed mechanism, the amine reacts with two molecules of alcohol in an electrophilic-nucleophilic cascade process. This procedure, if compared with the TiCl(3...
