Liu, Hangyu published the artcileSynthesis of formamides containing unsaturated groups by N-formylation of amines using CO2 with H2, Quality Control of 87179-40-6, the publication is Green Chemistry (2017), 19(1), 196-201, database is CAplus.
The selective and efficient N-formylation of amines containing unsaturated groups using CO2 and H2 with a Cu(OAc)2-4-dimethylaminopyridine (DMAP) catalytic system was described. The substrates were converted to the desired formamides, while the unsaturated groups, such as the carbonyl group, the C=C bond, CN bond and the ester group remained. The main reason for the excellent selectivity of the Cu(OAc)2-DMAP catalytic system was that it was very active for the N-formylation reaction, but was not active for the hydrogenation of the unsaturated groups.
