    • -1, respectively, as determined by plasma emission spectroscopy. For the Si(Zn) catalyst, activation for 2 h at 150°C under vacuum was necessary before use. Reactions carried out using thermal heating were performed in an oil bath under the same conditions of temperature and time as the microwave reactions. This temperature was determined at the end of a blank reaction using microwave irradiation.

    • The modified silicas were characterised by IR spectroscopy. Pyridine adsorption-desorption experiments were carried out in order to determine the relative proportion of Lewis and Brønsted acidic sites. Thus, Lewis/Brønsted acid area ratios were determined by the integral areas of Lewis and Brønsted IR bands of pyridine adsorbed onto modified silicas previously described by: Fraile, J. M.; García, J. I.; Mayoral, J. A.; Pires, E.; Salvatella, L.; Ten, M. J. Phys. Chem. B 1999, 103, 1664.
