Abstract: Treatment of 1-aryl-2-allylalkane-1,3-diones with I₂/H₂O₂ system in the presence of catalytic amount of phosphomolybdic acid affords furo[2,3-c][1,2]dioxole derivatives. With other acidic catalysts such as BF₃ · Et₂O, SnCl₄, H₂SO₄ or TsOH, mixtures with linear 4-acyloxy-2,5-diiodoalkan-1-ones are formed.

Keywords: furo[2,3-c][1,2]dioxoles, iodination, peroxides, cyclization, hydrogen peroxide, iodine, acetals, phosphomolybdic acid, catalysis.
