Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

Advanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,

Rhodium‐Catalyzed Oxidative CH o‐Arylation of s‐Aryltetrazines with Aryl Boronic Acids: One‐Step Selective Access to T‐Shaped and Z‐Shaped Polyaromatics

Advanced Synthesis &Catalysis, EarlyView.
A one‐step regioselective access to T‐Shaped and Z‐Shaped polyaromatics s‐tetrazines by a rhodium‐catalyzed oxidative CH o‐functionalization is reported. Electron‐rich aryl coupling partners display a higher reactivity than electron‐poor aryl, and allow the formation of poly(hetero)aromatic derivatives while avoiding 1,4‐azaphilic addition of the ...

Solvent‐Free Mechanocatalytic Reduction of Nitro Compounds with Hydrogen Gas and its Application in the Synthesis of Drugs and their Intermediates

Advanced Synthesis &Catalysis, EarlyView.
A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.
