Carbon　dioxide　(CO2),　a　readily　available,　non-toxic,　and　inexpensive　greenhouse　gas,　is　an　ideal　reagent　for　carbamate　synthesis.　For　the　first　time,　CO2　has　been　efficiently　incorporated　into　a　novel　nitrile-containing　directing　group　(DG)　for　meta-C-H　activation　of　anilines　under　mild　conditions.　Thus,　various　aniline　derivatives　were　metaolefinated　with　palladium(II)　acetate.　meta-C-H　acetoxylation　was　also　feasible　and　the　carbamate　DG　could　be　easily　removed　under　basic　conditions.　The　practicality　of　substrate　preparation,　functional　group　tolerance,　and　versatility　of　this　method　make　it　a　valuable　addition　to　the　meta-C-H　functionalization　of　anilines.
