A new superacid, H(CB11H6X6) (where X = chlorine or bromine), whose conjugate base is the exceptionally inert CB11H6X6- carborane anion, separates Bronsted acidity from oxidizing capacity and anion nucleophilicity in a manner not previously achieved. Reaction of this superacid with C60 gives HC60+ as a stable ion in solution and in the solid state. In a separate experiment, an oxidant was devel...
so42-/zno-tio2 catalyst was prepared by sulfating zno-tio2 powders with h2so4 solution. the catalyst was characterized by xrd, ir and hammett indicator. the catalyst showed strong acidity(h0 ≦-16.0). the optimum conditions are found that the calcination temperature is 823k and the soaked consistency of h2so4 is 1 mol/dm3. then so42-/zno-tio2 was applied as the catalyst in the catalytic synthesi...
Liquid-phase Benzene Isopropylation Using Alumina Solid Lewis Superacid-supported Platinum Catalyst.
Dodoneine (Ddn) is one of the active compounds identified from Agelanthusdodoneifolius, which is a medicinal plant used in African pharmacopeia and traditional medicine for the treatment of hypertension. In the context of a scientific program aiming at discovering new hypotensive agents through the original combination of natural product discovery and superacid chemistry diversification, and af...
One-electron oxidation converts the ferrocene-substituted borane into a Lewis superacid, as reported by Frank Breher, Jan Paradies, and co-workers in their Communication (e202216959). The superacid activates almost inert carbon–fluorine sulfur–fluorine bonds for reductions, alkylations, arylations to form new chemical bonds.
