Asymmetric electrophilic fluorination using an anionic chiral phase-transfer catalyst.
The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. Here, we present evidence that a largely overlooked analogous mechanism wherein a chiral anioni...

Translation as the Catalyst of Cultural Transfer
This essay reflects on the many different strategies involved in translation, which is both a linguistic and a cultural-historical strategy. Examples from the Middle Ages and the Modern Age are adduced to illustrate the huge impact which translations have had on peoples and societies throughout time.
متن کاملPhosphinates as new electrophilic partners for cross-coupling reactions.
The use of enol phosphinates as electrophiles for cross-coupling reactions has been explored. Both boronic acids (Suzuki-Miyaura reaction) and stannanes (Stille reaction) couple efficiently with lactam derived phosphinates.
متن کاملImidazole catalysis. II. Acyl transfer and the reactions of acetyl imidazole with water and oxygen anions.
Catalysis of p-nitrophenyl acetate hydrolysis by imidazole and its derivatives has been described in a number of investigations, of which the most extensive are those by Bruice and Schmir and by Bender and Turnquest (2-9). Imidaaole catalysis of the transfer of activated acyl groups from acyl phosphates to a number of acceptor molecules, which is a model for carboxylactivating enzymes and trans...
