This review summarizes the recently developed photocatalytic strategies for the installation of the formyl group into various scaffolds.
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 generic structures of solvents that can effectively promote the reduction of CO2 with phenylsilane were obtained in this work.
