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

Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves

Abstract While arylazo sulfones have been widely applied as arylating agents, their exploitation for diazenylation reactions has been previously limited to electron‐rich alkenes such as styrenes and silyl enol ethers. Herein we optimized a synthetic one‐pot protocol to access oxazolyl azo compounds via a selective domino ring‐closing/aryldiazenylation ...

Improving the Photochemical Skeletal Enlargement of Pyridines to 1,2‐Diazepines with Isocyanates
Abstract In this work, we extend the one‐pot protocol to synthesize 1,2‐diazepines from commercially available and cheap starting materials. Capitalizing on isocyanate derivatives as activating agents, the photochemical skeletal enlargement occurs, while preserving key functional groups embedded in more than 30 substrates.
