Conclusions
In summary, we have developed the first Rh(I)-catalyzed regio-
selective arylcarboxylation of electron-deficient acrylamides
with CO2 under redox-neutral conditions. A range of acryl-
amides and arylboronic acids were suitable for this reaction,
leading to a series of malonate derivatives that could be con-
verted into other important structures such as oxindoles.
Preliminary mechanistic studies indicated the importance of
the rhodium enolate. Further investigation of the Rh-catalyzed
carboxylation strategy with CO2 is underway in our laboratory.
