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.
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.
The sustainable catalytic transformation of carbon dioxide into fine chemicals with high efficiency is a global challenge as although CO2 is an abundant, nontoxic, and sustainable carbon feedstock but also a critical factor for the Greenhouse Effect.
