Abstract Styrylboronic acid, C8H9BO2, was one of several organoboron compounds investigated for their wood-preservation properties following in situ polymerization. The structure consists of independent monomeric mol-ecules bound together by strong hydrogen bonds (B--O--H... O). The planes of the styryl and boronic acid moieties are twisted by 26 (1) with respect to each other, apparently as a result of the hydrogen-bonding requirements.
