Аннотация: The highly acidic Amberlyst-15 cationite is shown to be an effective catalyst for the Friedel–Crafts reaction between α-hydroxy phosphonates and phenols, resulting in the novel areno[d]oxaphosphole derivatives. Its advantages over p-toluenesulfonic acid are an increase in the yield of reaction products by 10–20% and the possibility of reusing the catalyst, i.e. reducing the cost of the entire procedure.

Ключевые слова: areno[d][1,2]oxaphospholes, α-hydroxy phosphonates, phenols, Amberlyst-15, Abramov reaction, Friedel–Crafts reaction.
