Bis(phenanthroline)-ligated copper complexes are important photocatalysts in 𝘃𝗶𝘀𝗶𝗯𝗹𝗲-𝗹𝗶𝗴𝗵𝘁-𝗱𝗿𝗶𝘃𝗲𝗻 𝗼𝗿𝗴𝗮𝗻𝗶𝗰 𝘀𝘆𝗻𝘁𝗵𝗲𝘀𝗶𝘀. Compared with conventional ruthenium- and iridium-based photocatalysts, copper offers advantages in terms of abundance and cost.

Ligand design enables the tuning of their photophysical and redox properties, allowing these complexes to participate in 𝘀𝗶𝗻𝗴𝗹𝗲-𝗲𝗹𝗲𝗰𝘁𝗿𝗼𝗻 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿 (𝗦𝗘𝗧) processes and promote radical generation and subsequent bond formation.

Representative examples include Cu(dpp)2PF6 (doi.org/10.1038/s41586…) and Cu(dap)2Cl (doi.org/10.1021/jacs.2…).

These copper photocatalysts have been applied in diverse transformations, including radical addition, C–C and C–heteroatom bond formation, oxidation, and kinetic resolution.

Owing to their tunable properties and broad synthetic applications, bis(phenanthroline)-ligated copper complexes represent promising alternatives to ruthenium- and iridium-based photocatalysts in suitable organic transformations and provide opportunities for developing diverse visible-light-driven synthetic methods.

1-Arylcyclobutanols are strained four-membered-ring compounds that offer versatile opportunities for C–C bond cleavage and ring-opening transformations. The substantial ring strain of cyclobutane provides a thermodynamic driving force for ring opening, while the hydroxyl group enables distinct activation pathways.

1-Arylcyclobutanols undergo ring-opening reactions through two main pathways: 𝘁𝗿𝗮𝗻𝘀𝗶𝘁𝗶𝗼𝗻 𝗺𝗲𝘁𝗮𝗹-𝗰𝗮𝘁𝗮𝗹𝘆𝘇𝗲𝗱 𝗿𝗶𝗻𝗴 𝗼𝗽𝗲𝗻𝗶𝗻𝗴 and 𝗿𝗮𝗱𝗶𝗰𝗮𝗹-𝗺𝗲𝗱𝗶𝗮𝘁𝗲𝗱 𝗿𝗶𝗻𝗴 𝗼𝗽𝗲𝗻𝗶𝗻𝗴.

In transition metal-catalyzed reactions, deprotonation of the hydroxyl group generates a metal alkoxide intermediate, which undergoes β-carbon elimination to form a γ-oxoalkylmetal intermediate. Palladium and rhodium catalysts are commonly used in this type of transformation.

In radical-mediated reactions, alkoxy radicals undergo β-scission to release ring strain, producing γ-ketoalkyl radicals that participate in subsequent bond-forming reactions.

These two activation modes provide complementary approaches to C–C bond cleavage and expand the synthetic utility of 1-arylcyclobutanols as versatile building blocks.
