Reactions of 2-formylphenylboronic acid with N-substituted hydroxylamines lead to nitrones which undergo partial anhydride formation at the boronic acid group.The crystallized intermediates of variable composition are converted by esterification with catechol or ethylene glycol into stable defined arylboronate complexes with a cyclic B,N-betaine structure.
