METHOD OF CARBON MONOXIDE FIXATION AND METHOD OF AMINE FORMYLATION

The present invention relates to a method for fixing carbon monoxide in a metal-free condition and a method for formating amine using the same.

Mn(II)-Catalyzed N -Acylation of Amines

A practical protocol has been developed here for the Mn(II)-catalyzed N -acylation of amines with high yields using N, N -dimethylformamide and other amides as the carbonyl source. The protocol is simple, does not require any acid, base, ligand, or other additives, and encompasses a broad substrate scope for primary, secondary, and heterocyclic amines.

Catalyst-Free Transamidation of Aromatic Amines with Formamide Derivatives and Tertiary Amides with Aliphatic Amines

A simple catalyst- and promoter-free protocol has been developed for the transamidation of weakly nucleophilic aromatic amines with formamide derivatives and low-reactivity tertiary amides with aliphatic amines. This strategy is advantageous because no catalyst or promoters are needed, no additives are required, separation and purification is easy, and the reaction is scalable. Significantly, this strategy was further applied to synthesize several pharmaceutical molecules on a gram scale, and excellent yields were achieved.

Metal-free Carbon Monoxide (CO) Capture and Utilization: Formylation of Amines

The capture and utilization of CO by 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) were performed in the absence of transition-metal complexes. The reaction of TBD with CO afforded TBD-CO adducts, which were converted to formylated TBD (TBD-CHO). TBD-CO adducts may include an interaction of CO with positively charged species based on NMR and IR analysis. In the presence of amines, CO was transferred from TBD-CO to amines, producing formylated amines with good yields. The reaction mechanism involving TBD-CO adducts is presented based on theoretical calculations. (Figure presented.).
