A combination of weak Lewis acid (LiCl) and weak Bronsted acid (hexafluoroisopropanol, HFIP) promotes efficiently the Friedel-Crafts reaction of electron-rich arom. compds. with Et glyoxylate. [on SciFinder (R)] ...
Recently we reported on the synthesis and characterization of a series of very weakly coordinating anions (WCA's) of type Al(OR)4- (R=poly or perfluorinated aliph. alkoxide). These anions produce "Pseudo Gas Phase Conditions" in the solid state that allo ...
N-protected tropenone undergoes highly regioselective retro-Mannich reactions to 2-pyrrolyl ketones in the presence of Lewis or Bronsted acids. Analogously, a pyrrole deriv. was obtained by using subsequent nucleophilic trapping with trimethylsilanecarboni ...
Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O2 reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is possible to driv ...
A series of imidazolium dicarboxylic acids have been prepd. from the reaction of the 1,3-bis(carboxymethyl)imidazolium zwitterion with the Bronsted acids HX (X = F, Br, Cl, ClO4). The structures of these acids have been established in the solid ...
This article describes BP86/SV(P) (DFT) calcns. on a representative set of weakly coordinating anions (WCAs) of type [M(L)n]-, their parent neutral Lewis acids M(L)n-1 and their ate complexes with fluoride, i.e., [FM(L)n]n-1 (M = B, L = F, OTeF5, C6H5, C6F ...
The work presents the effect of K-doping on V/Ti-oxides taking into account: the surface acid–base properties and the structure of surface vanadia species in respect to the catalyst performance and deactivation. The structure of active surface species dete ...
A one-dimensional (1-D) multi-component model accounting for hydrological transport inorganic equilibrium chemistry and microbial activity during kinetically controlled biodegradation in groundwater of compounds such as benzene, toluene, ethylbenzene and x ...
The influence of the acid/base properties of Mg2+-modified alumina on the steady-state and transient behavior of the EtOH to ethene dehydration was investigated by simultaneous gas phase and in-situ surface anal. The steady-state EtOH conversion and the et ...
Benzylic carbocations, which are easily generated in situ from alcohols or acetates by Brønsted or Lewis acids, undergo selective facial discrimination in diastereoselective reactions (see scheme; FG=functional group). The A values are responsible for the ...
