We demonstrate that electrochemical control of Scholl reaction can differentiate arenium cation and radical cation pathways, providing the experimental basis to re-evaluate previously proposed mechanisms for certain substrates. onlinelibrary.wiley.com/doi/…

We made another π-molecule of Möbius topology, using the Scholl reaction! Our most recent Angew. Chem. paper reports the divergent synthesis of a Möbius N-heterocycloarene and a Hückel N-heterocycloarene from a common macrocyclic backbone. onlinelibrary.wiley.com/doi/…

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

In the divergent synthesis of Möbius and Hückel N-heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while...

Be afraid be very afraid of black flames! In flame tests excited electrons in sodium in table salt emit almost monochromatic yellow at 589 nm. A low pressure sodium lamp also emits the same λ. The flame also absorbs that light & appears black. #spookychemistry 🔥

Have polyacenes really been synthesized? I'm not convinced by the characterization with solid NMR, FTIR and other methods. Don't forget pentacene and larger acenes easily dimerize and are oxidized by molecular oxygen.
