The significant acceleration in the Kabachnik-Fields reaction in an external magnetic field has been observed. The phenomenon is explained by the proper orientation of substrate molecules forced by external magnetic field. Diamagnetic dipoles are repulsed to the center by both electromagnet poles, being simultaneously arranged. This phenomenon may then promote the acceleration of the reaction.
Effects of a Constant Magnetic Field on the Electrochemical Reactions of Quercetin

The paper presents a study of the effect of a constant magnetic field (CMF) on the basic processes of quercetin electrochemical reactions. According to the observation made in previous studies, the presence of a double bond in the C-ring of quercetin enhances the antioxidant properties of that compound, whereas the presence of ?OH groups also affects the antioxidant properties. Using cyclic voltammetry it was found that the constant magnetic field improves the efficiency of quercetin electrooxidation, especially of the third stage of the process, i. e. the stage in which the oxidation of the OH groups in the A-ring is the most difficult. The use of HPLC confirmed the electrochemical measurements and the results of cyclic voltammetry studies. The beneficial effect of the magnetic field on the efficiency of quercetin oxidation was confirmed by the results of impedance spectroscopy measurements.
