Using Restricted Bond Rotations to Enforce Excited-State Behavior of Organic Molecules
Publisher: Georg Thieme Verlag KG
Date: 02-03-2022
DOI: 10.1055/A-1785-6910
Abstract: This account highlights the role of restricted bond rotations in influencing the excited-state reactivity of organic molecules. It highlights the photochemical reactivity of various organic molecules and the design strategies that could be exploited by chemists to utilize restricted bond rotations to uncover new excited-state reactivity and to achieve selectivity. 1 Introduction. 2 NEER-Principle and Restricted Bond Rotations in the Excited State 3 [2+2]-Photocycloaddition of Enamides 4 [3+2]-Photocycloaddition vs. Paternò–Büchi Reaction of Enamides 5 Divergent Photoreactivity of Enones Dictated by Restricted Bond Rotations: Norrish–Yang reactions vs. 6π-Photocyclization 6 Divergent Photoreactivity of Imides with Alkenes: [2+2]-Photocycloaddition vs. Photoene Reaction 7 Summary and Outlook
Energy Transfer Catalysis by Visible Light: Atrop‐ and Regio‐Selective Intermolecular [2+2]‐Photocycloaddition of Maleimide with Alkenes
Publisher: Wiley
Date: 08-11-2019
Abstract: Intermolecular [2+2]‐photocycloaddition of atropisomeric phenyl maleimide has been evaluated with substituted alkenes with complete control over regiochemistry. We were also successful in carrying out atropselective reactions with the removal of axial chirality leading to enantio‐enriched photoproducts. Based on detailed photophysical studies, a mechanistic rationale is proposed for the observed selectivity.
Realizing the Photoene Reaction with Alkenes under Visible Light Irradiation and Bypassing the Favored [2 + 2]-Photocycloaddition.
Publisher: American Chemical Society (ACS)
Date: 26-09-2018
DOI: 10.1021/JACS.8B08100
Abstract: The textbook photoreaction between two alkenes is the [2 + 2]-photocycloaddition resulting in functionalized cyclobutanes. Herein, we disclose an unusual reactivity of alkenes that favor photoene reaction over the [2 + 2]-photocycloaddition.
