I found the field of Chemistry very interesting. Saw the article Distinctive reactivity of N-benzylidene-[1,1 ‘-biphenyl]-2-amines under photoredox conditions published in 2020. Application In Synthesis of 3-Pyridinecarboxaldehyde, Reprint Addresses Cho, EJ (corresponding author), Chung Ang Univ, Dept Chem, 84 Heukseok Ro, Seoul 06974, South Korea.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde
A simple photocatalytic method was developed for the synthesis of unsymmetrical 1,2-diamines by the unprecedented reductive coupling of N-benzylidene-[1,1′-biphenyl]-2-amines with an aliphatic amine. The presence of a phenyl substituent in the aniline moiety of the substrate was critical for the reactivity. The reaction proceeded via radical-radical cross-coupling of alpha-amino radicals generated by proton-coupled single-electron transfer in the presence of an Ir photocatalyst. On the other hand, symmetrical 1,2-diamines were selectively produced from the same starting materials by the judicious choice of the reaction conditions, showcasing the distinct reactivity of N-benzylidene-[1,1′-biphenyl]-2-amines. The developed method can be employed for the synthesis of various bulky vicinal diamines, which are potential ligands in stereoselective synthesis.
