This paper describes an optimized microwave irradiation-assisted methodol. for halogen-halogen exchange reactions on various substituted pyridines. The protocol provides an efficient and simple methodol. to improve the reactivity of some positions on the pyridine ring towards metallocatalyzed reactions. Influence of various substituents were explored and limiting factors of reaction highlighted. In addition to this study using 5-Bromo-2-chloropyridine, there are many other studies that have used 5-Bromo-2-chloropyridine(cas: 53939-30-3Category: pyridine-derivatives) was used in this study.
5-Bromo-2-chloropyridine(cas: 53939-30-3) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Category: pyridine-derivatives
