Chemoselective Acylation of Primary Amines and Amides with Potassium Acyltrifluoroborates under Acidic Conditions
TL;DR: This work describes an amide formation using primary amines and potassium acyltrifluoroborates promoted by simple chlorinating agents that proceeds rapidly in water and tolerates alcohols, carboxylic acids, and even secondary amines in the substrates.

Helicene Monomers and Dimers: Chiral Chromophores Featuring Strong Circularly Polarized Luminescence.
Cédric Schaack,Lorenzo Arrico,Eric Sidler,Marcin Górecki,Marcin Górecki,Lorenzo Di Bari,François Diederich +6 more
TL;DR: The synthesis and chiroptical properties of a series of enantiomerically pure, C2 -symmetrical carbo[6]helicene dimers are reported, which exhibit intense ECD spectra with strong bands in the UV/Vis region well above 400 nm.

Light-Responsive Pyrazine-Based Systems: Probing Aromatic Diarylethene Photocyclization
Jovana V. Milić,Cédric Schaack,Nora Hellou,Florin Isenrich,Renana Gershoni-Poranne,Dmytro Neshchadin,Sylvain Egloff,Nils Trapp,Laurent Ruhlmann,Corinne Boudon,Georg Gescheidt,Jeanne Crassous,François Diederich +12 more
TL;DR: In this article, the photocyclization of novel aromatic diarylethene (DAE) systems based on pyrazine, quinoxaline, and helicene scaffolds was investigated.
Remote Control of Dynamic Twistacene Chirality.
Si Tong Bao,Hao Jiang,Cédric Schaack,Shayan Louie,Michael L. Steigerwald,Colin Nuckolls,Zexin Jin +6 more
TL;DR: In this paper , the axial chirality in perylene diimide (PDI)-based twistacenes is manipulated to control the helicity of flexible [4]helicene subunits by UV-vis, CD spectroscopy, and X-ray crystallography.

Electric fields drive bond homolysis
Boyuan Zhang,Cédric Schaack,Claudia R. Prindle,Ethan Vo,Miriam Aziz,Michael L. Steigerwald,Timothy C. Berkelbach,Colin Nuckolls,Latha Venkataraman +8 more
TL;DR: In this article , the authors used the scanning tunneling microscope-based break-junction technique to investigate the electric field driven homolytic cleavage of the radical initiator 4-(methylthio)benzoic peroxyanhydride at ambient temperatures in bulk solution.
