We have constructed a highly crystalline 2D imine-linked Co(II)-incorporated Tp-TH COF catalyst (Co(II)@Tp-TH) with a band gap energy of 2.4 eV to serve as a stable and effective porous photocatalyst for the synthesis of N-formylated amines.
Supported Pt NP catalysts modified with basic [Nb6O19]8− facilitated the N-formylation reaction of amines using CO2 as a carbon source.
Photochemical conversion of various amines to N-formamides using CO2 under ambient conditions with a hybrid photocatalyst composed of zinc phthalocyanine grafted to g-carbon nitride in high to excellent yields has been described.
The N-formylation reaction of amines with DMF as a formylating agent was developed. N-Sulfonyl amidines were also obtained in good to excellent yields by the reaction of sulfonamides with DMF under similar conditions.
The selective N-formylation and N-methylation of amines with carbon dioxide (CO2) catalyzed by methyltriphenylphosphonium methylcarbonate and tuned by polymethylhydrosiloxane or trimethoxysilane as reducing agents is reported.
