Wei, Xiu-Zhi published the artcileTriethylamine Catalyzed Reductive CO2 to Form N-Formylation of Amines and Hydrazides, COA of Formula: C8H11NO, the main research area is formamide formyl hydrazide preparation; amine hydrazide carbon dioxide formylation triethylamine.

Carbon dioxide was one of the main green-house gas, using CO2 as a C1 source to produce functional chems. can relieve environmental issues. With the development of the N-formylation reaction of amines under a CO2 atmosphere, a promising route for the synthesis of diacylhydrazines is the N-formylation of hydrazide with CO2 in the presence of a reducing agent. Triethylamine (TEA) is an organic base commonly used in organic synthesis, which has a low b.p. to easily separated from the system by decompression distillation Authors herein describe TEA-catalyzed selective N-formylation of amines/hydrazide using CO2 and NaBH4 to construct various formamide and N’-formyl-hydrazide. Utilizing N-formylation of amines reaction to tune the reaction solvent, base, and temperature given a lower boiling catalyst and solvent system and the product can be separated easily. The selective synthesis method of formamides is achieved in good yields, which is also equally adapted to hydrazides. Finally, 1,3,4-oxadiazole skeleton having synthetic drugs and material application was obtained by cyclization of N’-formyl-hydrazide.

Du, Chongyang published the artcileZinc Powder Catalysed Formylation and Urealation of Amines Using CO2 as a C1 Building Block, Category: isoquinoline, the main research area is formamide preparation; secondary amine carbon dioxide formylation zinc catalyst; urea preparation; primary amine carbon dioxide urealation zinc catalyst.

The zinc powder catalyzed formylation and urealation of secondary amines e.g., N-methylaniline and primary aromatic amines RNH2 (R = Ph, 2,4,6-trimethylphenyl, cyclohexyl, etc.) with CO2 and (EtO)3SiH under solvent-free condition were reported. Using 2 mol% zinc powder as the catalyst, a series of secondary amines, both the aromatic ones and the aliphatic ones can be formylated into formamides e.g., N-methyl-N-phenylformamide. When primary aromatic amines were used as the substrates, the reactions produce urea derivatives RNHC(O)NHR. The electronic and steric effects from the substrates on the formylation and urealation reactions were observed and discussed. The recovery and reusability of zinc powder were investigated, showing that zinc powder can be reused in the formylation reaction without loss of catalytic activity. The anal. on the reactants/products mixture after filtering out the zinc powder showed that zinc concentration in the mixture is low to 1 ppm. The pathways for the formylation and urealation of amines with this catalytic system were also investigated and related to the different substrates.

Wang, Jixiao published the artcileUnsupported Nanoporous Palladium Catalyst for N-Formylation of Amines Using CO2 as a Sustainable C1 Source, COA of Formula: C8H11NO, the main research area is formamide green preparation; amine carbon dioxide formylation nanoporous palladium catalyst.

An efficient heterogeneous catalytic system for the synthesis of aryl formamides R1N(C(O)H)R2 [R1 = Ph, 4-MeC6H4, 2-MeOC6H4, etc.; R2 = H, Me, Bn, etc.; R1 = R2 = Ph, Bn, Cy, etc.] via N-formylation of amines using CO2 as a sustainable C1 source was developed using unsupported nanoporous palladium (PdNPore). The PdNPore-catalyzed N-formylation of amines and CO2 with hydrosilane proceeded smoothly under mild reaction conditions to yield formamides in satisfactory to excellent yields. No palladium leached from PdNPore during the hydrogenation reaction. Moreover, the catalyst was easily recovered and reused without any loss of catalytic activity. This study was the first to demonstrate that PdNPore catalyzed CO2 conversion to form C-N bond, which enriches the reaction types of CO2 conversion catalyzed by PdNPore catalyst.
