The enantioselective catalytic construction of structurally sophisticated helicenes integrating both helical and central chirality remains a formidable challenge, and organocatalytic strategies for helicene synthesis are still severely underexplored compared with transition-metal catalysis. Benefiting from the inhere...
The development of sustainable methods for the oxidation of alcohols to aldehydes or ketones remains an important goal in synthesis. In this work, we synthesized a series of nitrate‐bearing oxoammonium salts and demonstrated their efficiency as metal‐free catalysts for the aerobic oxidation of alcohols. These catal...

1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD) is a widely used bifunctional organocatalyst; however, its microscopic behavior in hydrogen-bonding environments remains poorly understood. In this study, we employed broadband rotational spectroscopy to identify the stepwise microhydration of TBD with one to four water molec...
