Rhodium-catalyzed C–H carboxymethylation of anilines with vinylene carbonate

Org. Biomol. Chem., 2023, Advance Article
DOI: 10.1039/D3OB00931A, Paper
Qiong Liu, Zhaolong Ma, Jing Zhang, Xu-Qin Li
We established a Rh(III) catalyzed C–H carboxymethylation strategy for anilines with vinylene carbonate. This protocol does not require external oxidants. It proceeded smoothly with good functional group tolerance and moderate to good yields.
