Harnessing Toluene Solvent as a Reactant: Regioselective Benzyl Radical Addition to Multi‐π 1,5‐Enynes in a Copper‐Catalyzed Cascade to Indenes

Chemistry – A European Journal, EarlyView.
A copper‐catalyzed three‐component radical cascade of 1,5‐enynes with toluene and benzoic acids enables regioselective benzyl radical addition to multi‐Π systems, efficiently delivering polysubstituted indenes from an abundant solvent feedstock. ABSTRACT C─H activation of toluene generates a benzyl radical that undergoes C─C coupling, converting an ...

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating
