WebMay 6, 2011 · In order to circumvent this issue, we investigated a transesterification procedure with diethanolamine (DEA) to form an sp 3-hybridized boron·DEA adduct, which is then hydrolyzed to yield a boronic acid derivative.Indeed, a few examples of pinacol deprotection with DEA have been reported, but most of these are arylboronic esters. … WebWe have developed an assay that uses phenyl boronate agarose column chromatography to measure the capping efficiencies of RNA polymerases used for in vitro transcription of cloned cDNAs.
A boronic acid is an organic compound related to boric acid (B(OH)3) in which one of the three hydroxyl groups (−OH) is replaced by an alkyl or aryl group (represented by R in the general formula R−B(OH)2). As a compound containing a carbon–boron bond, members of this class thus belong to the larger class of organoboranes. Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH)2 where Ph is the phenyl group C6H5-, is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic syn…
