2-Chloro-5-methylthiophene

2-Chloro-5-methylthiophene is an organic compound with a boronic acid group that allows cross-coupling reactions. This compound can be used as a building block for the synthesis of other boronate derivatives. It has been shown to react with amines in an acidic environment and can form stable molecules, which may have structural properties that are different from those of the original molecule. 2-Chloro-5-methylthiophene has been synthesized using X-ray crystal structures and spectroscopy techniques, which show its fluorescence properties. This compound also exhibits linker photochromism and cross-coupling functional groups.
