Organoboron Compounds – chem. database
From website: “Boronic acids and their esters are highly popular synthetic intermediates in organic synthesis for their ease and efficiency of conversion to other functional groups, in metal-catalyzed cross-coupling reactions and for their unique biochemical activity.The palladium-catalyzed cross-coupling reaction of organoboron compounds with organic halides or pseudo-halides – the Suzuki-Miyaura reaction – is a remarkably useful tool in organic synthesis.”
Synthesis references and physical data (melting/boiling point, refractive index, density) for more than 2,000 boronic acids, boronic acid esters and trifluoroborates. You can search for substance by chemical name and CAS number.
