Abstract

The template effect of metal ions such as Sn2+, Sb3+, Al3+, Zn2+, etc., on the synthesis of the title compound (I) from furan and Me2CO was studied. The effective ionic radii (r), the ratio of the ionic electronegativity (x'), and the ionic charge (z) of the metal ion are useful parameters in the choice of a template agent to give the optimum yield of I. Decreasing the ionic potential z/r of the counteranion affects the template effect of metal ion, increasing the product yield.

Key words: CONDENSATION REACTION, ZINC, ALUMINIUM, STIBIUM, TIN, CYCLOPENTADIENE P, FURAN P, MACROCYCLIC COMPOUNDS, ACETONE, FURAN
