Description and Uses
Pyridine-4-boronic acid is a kind of boronic acid derivative. It is useful building blocks in crystal engineering. It can also be used as a catalyst to act as a dehydrative condensation agent to synthesize amides using carboxylic acid and amines as raw materials. Its derivative, polystyrene-bound 4-pyridineboronic acid, is a useful catalyst for amidation reaction and esterification of alpha-hydrocarboxylic acids.
Boronic acid derivatives and their binding affinities with diols.
