Anomalous Glassy Thermal Conductivity in a Perovskite Bismuthate Induced by Structural Dynamic Instability

Advanced Science, EarlyView.
Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...

Water‐Catalytic Deconstructive and Proton Transfer Cyclopropanation of Sulfoxonium Ylide with Olefin

Advanced Science, EarlyView.
Water‐catalytic deconstructive and proton transfer cyclopropanation of sulfoxonium ylide with olefin is developed through a sequential water‐mediated ring‐closing/opening reaction. This atom‐economical, environmentally friendly methodology offers easy access to a range of cyclopropyl ketones with moderate to good yields.
