Hydrogen bonding mediated electron donor-acceptor acceptor catalysis in hydrosulfonylation and sulfonyl dehydrogenation of olefins [PDF]
Nature CommunicationsElectron donor-acceptor (EDA) acceptor catalysis remains significantly less developed than donor catalysis. Herein, a hydrogen-bond-mediated EDA acceptor catalysis using readily available 4,4'-di-tert-butyl-2,2'-bipyridine (dtbbpy) or 4-tert ...

Atropisomerism in Styrene: Synthesis, Stability, and Applications
SynOpen, 2021 Atropisomeric styrenes are a class of optically active compounds, the chirality of which results from restricted rotation of the C(vinyl)–C(aryl) single bond.

Carbene-catalyzed atroposelective synthesis of axially chiral styrenes
Nature Communications, 2022 Axially chiral styrenes bearing a chiral axis between a sterically non-congested acyclic alkene and an aryl ring are difficult to prepare due to low rotational barrier of the axis. Here the authors present a method to form axially chiral styrenes bearing
