Along our way towards the advanced saccharide-sensitive probes, three novel electroactive iminoboronate regioisomers of [(ferrocenylimino)methyl]phenylboronic acid have been synthesized. The ortho, meta, and para regioisomers were characterized structurally by NMR, MS, FT-IR, UV/Vis and their electrochemical behavior in aqueous solution was studied using cyclic voltammetry. The obtained results confirmed different behavior of the ortho isomer due to an interaction of boronic acid moiety with the proximate imine group of the iminoferrocenyl residue.
