Beilstein Journal of Organic Chemistry, 2013 A “stop-and-flow” strategy was developed for the chemoselective dioxygenation of alkenes with a PIFA-initiated cyclization. This method is conceived for the desymmetrization of seco-diene, and a series of substituted 5-hydroxymethyl-γ-lactones were ...

Anomeric Amide‐Enabled Alkene‐Arene and Alkene‐Alkene Aminative Coupling
Angewandte Chemie International EditionAbstractDespite the prominence of C−N bond forming cross‐coupling reactions as a strategy to assemble molecular fragments, aminative coupling approaches, in which two fragments are assembled directly at the heteroatom, represents a rarely exploited retrosynthetic strategy. Herein, we report the design, synthesis, and implementation of an anomeric amide

Reversible Alkene Binding and Allylic C–H Activation with an Aluminum(I) Complex [PDF]
, 2018 Reversible alkene binding to a low-valent main group complex is documented. The reaction involves an aluminium(I) reagent and includes both terminal and strained alkenes. This reversible binding event is just a forerunner to non-reversible C–H activation

Radical-Mediated Trifunctionalization Reactions
MoleculesSynthetic radicals have intrinsic power for cascading and multifunctional reactions to construct diverse molecular scaffolds. In the previous review series, we covered 1,2-difunctionalizations, remote 1,3-, 1,4-, 1,5-, 1,6-, and 1,7-difunctionalizations,

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS Open Bio, EarlyView.We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Photoinduced Electron-transfer Reaction of Pentafluoroiodobenzene with Alkenes
Molecules, 1997 Irradiation of pentafluoroiodobenzene and alkenes gave the corresponding adducts. The presence of single electron-transfer scavengers, (p-dinitrobenzene and t-Bu2NO) and the free radical inhibitor (hydroquinone) suppressed the reaction.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery
Advanced Engineering Materials, EarlyView.We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...
