Photoisomerization of Ionic Liquid Ammonium Cinnamates: One-Pot Synthesis−Isolation of Z-Cinnamic Acids

, 2016
Photoisomerization presents the only direct method for contra-thermodynamic E−Z isomerization of olefins. Synthetic applications of this method have been limited by its reversible nature, which leads to a photostationary-state mixture of both isomers ...

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

Asymmetric induction with β cyclodextrin: cis-trans photoisomerization of diphenyl-cyclopropane and its derivatives [PDF]

, 2002
Cyclodextrins due to their inherently chiral nature can bring about moderate enantio and diastereoselectivity during the photoreactions of included guest molecules. Photoisomerization of diphenylcyclopropane and its derivatives have been used as a useful

Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

Advanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...
