Site specific carboxylation of abnormal anionic N-heterocyclic dicarbenes with CO2

Site specific carboxylation of abnormal anionic N-heterocyclic dicarbenes with CO2

Herein, we report experimental and computational results for the carboxylation of abnormal anionic N-heterocyclic dicarbenes (NHDCs) with CO2. Under ambient dosing conditions, carbonyl addition occurs selectively at C4 without a second carboxylation event occurring at the C2 carbene center.
