Photoexcited arylketones catalyze the direct chlorination of C(sp3)–H groups by N- chlorosuccinimide. Acetophenone is the most effective catalyst for functionalization of unactivated C–H groups while benzophenone provides better yields for benzylic C–H functionalization. Activation of both acetophenone and benzophenone can be achieved by irradiation with a household compact fluorescent lamp. This light-dependent

To provide a method for producing an ethylenically unsaturated group-containing isocyanate compound having an ether bond under such conditions that the ether bond is unlikely to be cleaved and the polymerization of an unsaturated group can be suppressed. The method for producing an ethylenically unsaturated group-containing isocyanate compound having an ether bond of the present invention is a method for producing an ethylenically unsaturated double bond-containing isocyanate compound from an amino alcohol having an ether bond and is characterized in that a reaction solvent in which the solubility of hydrogen chloride is 0.1 mole percent or less at 25°C is used.
