title: Preparation and electrochemical behaviour of hydrophobic vitamin B(12) covalently immobilized onto platinum electrode.
abstract: Hydrophobic vitamin B(12) was covalently immobilized onto a platinum electrode surface, and the immobilized complex exhibits Co(ii)/Co(i) redox couple and in situ the Co(i) species reacts with phenethyl bromide to form styrene under irradiation with visible light with a turnover number of over 6000 for 1 h.
