Applications
Boronic acids react with alcohols, with loss of water, to form boronic esters. With simple alcohols, the products are very susceptible to hydrolysis, but with 1,2- and 1,3-diols, the resulting cyclic boronates (1,3,2- dioxaborolanes and 1,3,2-dioxaborinanes) are stable enough to be isolated.

Solubility
Difficult to mix in water.

Notes
Store at room temperature. Incompatible with oxidizing agents.
