4-Methylbenzeneboronic acid

Description:

4-Methylbenzeneboronic acid, also known as p-tolylboronic acid, is an organoboron compound characterized by the presence of a boronic acid functional group attached to a methyl-substituted benzene ring. Its molecular formula is C7H9B O2, and it features a boron atom bonded to a hydroxyl group and an aryl group, which in this case is a para-methylphenyl group. This compound is typically a white to off-white solid that is soluble in polar organic solvents and water, making it useful in various chemical reactions. 4-Methylbenzeneboronic acid is particularly significant in organic synthesis, especially in Suzuki coupling reactions, where it serves as a versatile building block for the formation of carbon-carbon bonds. Its boronic acid functionality allows it to form reversible complexes with diols, which is advantageous in various applications, including drug development and materials science. Additionally, it exhibits properties that make it useful in sensor technology and as a reagent in the synthesis of biologically active compounds.
