Abstract:
Carbonyl-containing compounds serve as essential building blocks in various synthetic processes. However, due to the high bond energy of the C═O double bond, the traditional deoxygenation methods often require harsh conditions or toxic reagents. Direct carbonyl deoxygenative coupling of aldehydes and ketones is still challenging under mild conditions. Herein we report the successful establishment of an electroreductive coupling strategy utilizing aromatic carbonyls and terephthalonitrile. A key component of our approach is the use of closo-boranes, specifically (Et4N)2B10H10, which serve as an in situ deoxidant by single-electron oxidation.

Acid-Catalyzed α-Halogenation of Aldehydes and Ketones
In the first step of the mechanism, the acid protonates the carbonyl oxygen resulting in a resonance-stabilized cation, which subsequently loses an α-hydrogen to form an enol tautomer. The C=C bond in an enol is highly nucleophilic because of the electron-donating nature of the –OH group. Consequently, the double bond attacks an electrophilic...
