Applications · 2 items

Uses2,3,5-Trichloropyridine may be used in the synthesis of 3,5-dichloro-2-arylpyridines via palladium acetate-catalyzed ligand-free Suzuki reaction with arylboronic acids.

General DescriptionSeparation and migration behavior of 2,3,5-trichloropyridine has been studied by micellar electrokinetic chromatography. Crystal structure of 2,3,5-trichloropyridine has been reported. Mol-ecules of 2,3,5-trichloropyridine in crystal are stacked along the short a axis and forms a layer structure. 2,3,5-Trichloropyridine is reported to undergo nucleophilic displacement reaction in ionic liquid to afford the corresponding 2-aryloxylpropionate.
