Abstract

A process for preparing formylphenylboronic acids of the formula (I) by reaction of protected chlorobenzaldehydes of the formula (II) with lithium in an inert solvent to form compounds of the formula (III) and subsequent reaction with a boron compound of the formula BY3 to give compounds of the formula (I).
