Abstract

Water was magnetized via an external magnetic field and employed, for the first time, as a solvent in green preparation of 3,4-dihydropyrimidin-2(1H)-ones by the one-pot three-component condensation reaction using boric acid as a catalyst. Shorter reaction times, higher yields, and cleaner reaction profiles were some advantages of using magnetic water.

  • Three mechanisms have been proposed for how the magnetic eld affects water particles: (I) the spontaneous formation and collapse of cationic metal colloidal units in the interaction of magnetism and water, which leads to increase sedimentation in water; (II) the change in polarization of the dissolved ions in the water, the shape and size of the hydration layer cause some variations in the water properties; and (III) due to the polarity of the water molecules, the magnetic eld will directly affect the nature of the water molecules, the third mechanism is largely consistent with the experiments performed.[7]
