flow‐assisted synthesis of [10]CPP in four steps undermildconditions. For the synthesis, a selective nucleophilic addition of the unprotected diketone without the double‐added byproduct was achieved within 3 s in high yield. Subsequently, the obtained compound was reacted with dilithiated benzene at 25 °C to form a U‐shaped precursor for CPP in a separate microreactor, which was finally dimerized and aromatized

McMurry coupling of 4-phenylcyclohex-3-en-1-one and double addition of 1,4-dilithiobenzene and 4,4'-dilithiobiphenyl to cyclohexanones gives linear chains of three or four six-membered carbocyclic rings, including a potential intermediate in a proposed synthesis of [06]paracyclophane.

Oxidative α-C–C Bond Cleavage of 2° and 3° Alcohols to Aromatic Acids with O<sub>2</sub> at Room Temperature via Iron Photocatalysis
cleavage of unfunctionalized secondary (2°) and tertiary alcohols (3°) is essential for valorization of macromolecules and biopolymers. We developed a blue-light-driven iron catalysis for aerobic oxidation of 2° and 3° alcohols to acids via α-C–C bond cleavages at room temperature. The first example of oxygenation of the simple tertiary alcohols was reported. The iron catalyst and blue light play critical
