Reagent for protection of diols as their cyclic boronates: J. Am. Chem. Soc., 80, 2443 (1958); Tetrahedron, 25, 477 (1969), which are also useful in GC and GC-MS. This has been utilized to trap cis-diols, in order to prevent over-oxidation during dihydroxylation reactions catalyzed by Osmium(VIII)- oxide: Chem. Lett., 1721 (1988); J. Org. Chem., 63, 7322 (1998).
Promotes the ortho-hydroxalkylation of phenols by aldehydes. The cyclic boronate, formed via a [3,3] sigmatropic rearrangement, is the key intermediate: Synthesis, 365 (1979).
The most widely-used reaction of arylboronic acids is the Pd-catalyzed Suzuki synthesis of unsymmetrical biaryls: Synth. Commun., 11, 513 (1981).
For illustrative example, see: Org. Synth., 75, 53 (1997).
