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 ...

A novel n‐type dimer dopant for semiconducting polymers
A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.
