Skeletal editing is a straightforward synthetic strategy for precise substitution or rearrangement of atoms in core ring structures of complex molecules; it enables quick diversification of compounds that is not possible by applying periphe...
Light-driven ammonia synthesis under mild conditions using lithium hydride [0.03%]

Photon-driven chemical processes are usually mediated by oxides, nitrides and sulfides whose photo-conversion efficiency is limited by charge carrier recombination. Here we show that lithium hydride undergoes photolysis upon ultraviolet ill...
A molecular-level mechanistic framework for interfacial proton-coupled electron transfer kinetics [0.03%]

Electrochemical proton-coupled electron transfer (PCET) reactions can proceed via an outer-sphere electron transfer to solution (OS-PCET) or through an inner-sphere mechanism by interfacial polarization of surface-bound active sites (I-PCET...
A general alkene aminoarylation enabled by N-centred radical reactivity of sulfinamides [0.03%]

Arylethylamines are popular structural elements in bioactive molecules but are often made through a linear series of synthetic steps. A modular protocol to assemble arylethylamines from alkenes in one step would represent a useful advance i...
Chiral arylsulfinylamides as reagents for visible light-mediated asymmetric alkene aminoarylations [0.03%]

Two- or one-electron-mediated difunctionalizations of internal alkenes represent straightforward approaches to assemble molecular complexity by the simultaneous formation of two contiguous Csp3 stereocentres. Although racemic versions have ...
Structural characterization and reactivity of a room-temperature-stable, antiaromatic cyclopentadienyl cation salt [0.03%]
室温稳定的抗芳香环戊二烯阳离子盐的结构特征和反应性研究

The singlet states of cyclopentadienyl (Cp) cations are considered as true prototypes of an antiaromatic system. Unfortunately, their high intrinsic reactivity inhibited their isolation in the solid state as a salt, and controlled reactions...
Directed ultrafast conformational changes accompany electron transfer in a photolyase as resolved by serial crystallography [0.03%]

Charge-transfer reactions in proteins are important for life, such as in photolyases which repair DNA, but the role of structural dynamics remains unclear. Here, using femtosecond X-ray crystallography, we report the structural changes that...
Surface stratification determines the interfacial water structure of simple electrolyte solutions [0.03%]
表面分层决定了简单电解质溶液的界面水结构

Yair Litman et al.
The distribution of ions at the air/water interface plays a decisive role in many natural processes. Several studies have reported that larger ions tend to be surface-active, implying ions are located on top of the water surface, thereby in...
Analogies between photochemical reactions and ground-state post-transition-state bifurcations shed light on dynamical origins of selectivity [0.03%]

Revealing the origins of kinetic selectivity is one of the premier tasks of applied theoretical organic chemistry, and for many reactions, doing so involves comparing competing transition states. For some reactions, however, a single transi...

The activation of dioxygen at haem and non-haem metal centres, and subsequent functionalization of unactivated C‒H bonds, has been a focal point of much research. In iron-mediated oxidation reactions, O2 binding at an iron(II) centre is of...
