UV-irradiation of 2-chloroacetophenones and olefins in the presence of silver triflate affords naphthalenone derivatives with high regio and stereoselectivity and chemical yields. A possible mechanism is proposed.

Under UV irradiation with 2-chloroacetophenone in the presence of silver trifluoromethanesulfonate in acetonitrile, acyclic olefins gave naphthalenone derivatives, while cyclic olefins gave phenanthrenone derivatives in moderate yields.

AbstractThe reactions of diaryl-, aryl-, and alkyl–arylcyclopropanes with ethyl nitrite in the presence of sulfur trioxide and sulfur trioxide dioxane complex, as well as the reactions of 1-alkyl-2-arylcyclopropanes with NOBF4 were studied. It was found that the attack of the nitrosonium cation, accompanied by the formation of a benzyl carbocation, leads to the formation of isoxazolines. The introduction
