TLDR
This Review closes this gap by providing a clear definition of ACDC and by examining both clear cases as well as more ambiguous examples to illustrate the differences and overlaps with other catalysis concepts.Abstract:
Recently, the use of enantiomerically pure counteranions for the induction of asymmetry in reactions proceeding through cationic intermediates has emerged as an exciting new concept, which has been termed asymmetric counteranion-directed catalysis (ACDC). Despite its success, the concept has not been fully defined and systematically discussed to date. This Review closes this gap by providing a clear definition of ACDC and by examining both clear cases as well as more ambiguous examples to illustrate the differences and overlaps with other catalysis concepts.read more

Advances in catalytic enantioselective fluorination, mono-, di-, and trifluoromethylation, and trifluoromethylthiolation reactions.
TL;DR: A combination of the increasing importance of fluorine-containing molecules and the successful development of bench stable, commercially available fluorine sources has brought the expansion offluorine chemistry into the mainstream organic synthesis community, resulting in an acceleration in the development of new fluorination methods and consequently in methods for the asymmetric introduction of fluoride.

Enantioselective catalysis of photochemical reactions.
TL;DR: This Review outlines the two major concepts of homogenously catalyzed enantioselective processes and reactions are presented in which the photochemical excitation is mediated by an achiral photocatalyst and the transfer of chirality is ensured by a second chiral catalyst (dual catalysis).
