A convenient synthesis of 1,1'- and 1,2'-dinaphthylmethanones

摘要

Because of their increased ability to absorb UV radiation (4 times that of benzophenone), dinaphthylmethanones (DNMs) are considered a new generation of UV-absorbing agents. In addition, because of their high electron density, favorable symmetry and stability, they are used to synthesize polyaryl ethers and ketones. They also serve as intermediates for the preparation of dyestuffs, electronic devices, coatings and other commercial products. Therefore, an effective synthesis for DNMs is needed and is a goal of our current research.
