An eco-friendly and direct arylation of hydroxyaryls in water using photoinduced reactions with different substrates (1-bromo-2-naphthol, 1-iodo-2-naphthol, N-(2-iodophenyl)acetamide, 5-bromouracil, 2-iodo-N-methylbenzamide, and 2-iodobenzamide) was studied. For example, π-expanded coumarins, compounds with potential optical applications, were synthesized in very high yield, without the use of toxic reagents, in a one-pot reaction. In addition, we demonstrate that the irradiation source (halogen lamp) can be efficiently replaced by an LED without altering the reaction yield.

Diaryliodonium Salts

Direct arylation of 2-substituted malononitriles using diaryliodonium salts without involving transition-metal catalysts was developed. By using potassium tert-butoxide as a promoter, the desired 2-substituated α-arylmalononitriles derivatives were synthesized in good to excellent yields of 55–96%. This synthetic method provided an efficient way to prepare a variety of 2-substituted arylmalononitriles which were useful in agrochemicals.
