    • The temperature on the microwave oven was set at 105 -C, but due to the small quantities used and the design of the temperature probe holder assembly, the sensor did not actually contact the reactants. The temperature measured just above the reaction mixture, however, never exceeded 90 -C

    • When we repeated the procedure described by Brossi and co-workers using Attenburrow MnO2 in acetic acid (120 -C, 4 h) for the conversion of 1j to 2j, we obtained a 15% yield. It must be noted, however, that the source of the MnO2 used in these earlier references was not reported.
