Abstract
The treatment of 2-methylfuran with phosphoric acid yields the 2,4,4-tris(5′-methyl-2′-furyl)-1-pentanol (1) as a tetrameric product. This product gives its acetate (2) on acetylation with acetic anhydride, and forms a equimolar adduct (3) after treatment with maleic anhydride. The structural formula of 1 is supported by the IR, UV, NMR, and mass spectral data and by the other experimental facts. The other oligomers are separated as a product (4) which contains tetra-, penta-, hexa-, and heptamer. The structure of these oligomers discussed, and some possible reaction mechanisms for oligomerization are suggested.
