General description

6-Bromo-2-pyridinecarboxaldehyde is a pyridine derivative. It participates in the synthesis of meso-substituted trans-A2B2-porphyrin.

Application

6-Bromo-2-pyridinecarboxaldehyde may be used in the synthesis of:
  • 6-([2,2′-bi(1,3-dithiolylidene)]-4-yl)picolinaldehyde
  • tris(2-pyridylmethyl)amine (Tpy) derivative having Tpy core bearing a 3-formyl-phenyl substituent on one of the three arms
  • syn- and anti- forms of 4-(6-bromopyridin-2-yl)-3-methyl-3-phenyloxetan-2-one
  • 6-(2,4,6-triisopropylphenyl)-2-pyridinecarboxaldehyde
Substrate used in a study of a rhodium-catalyzed, reductive aldol coupling with divinyl ketones leading to syn ß-hydroxyenones.
Useful building block for Tris[(pyridyl)methyl]amine ligands.

The synthesis and full characterization of two tetrathiafulvalene-appended azine ligands, namely 2-([2,2'-bi(1,3-dithiolylidene)]-4-yl)-6-((2,4-dinitrophenyl)hydrazono)methyl)pyridine (L1) and 5-([2,2'-bi(1,3-dithiolylidene)]-4-yl)-2-((2,4-dinitrophenyl)hydrazono)methyl)pyridine (L2) are described. The crystal structure of ligand L1 indicates that the ligand is completely planar with the presence of a strong intramolecular N3-H3···O1 hydrogen
