Photochemical Transformation of Methyl Coumalate

This application note illustrates the advantages of the UV-150 in performing continuous photochemistry against a published batch photochemical method demonstrating precise irradiation time, temperature control and wavelength selectivity . The 4π electrocyclisation of methyl coumalate shows an eight fold decrease in reaction times, an eight fold decrease in the amount of solvent used, a thirty fold decrease in the energy consumed by the lamp and switches to a greener solvent using acetonitrile compared to dichloromethane.
