Zusammenfassung:In this work, we demonstrate that the performance of mechanochemically activated transesterification and alkene metathesis catalysts is significantly enhanced when the thermal effects of ultrasound are suppressed. Suppression of these effects is realized by performing the reaction under methane instead of argon. Not only do these results provide further confirmation of the true mechanochemical nature of the ultrasonic activation of the catalysts, but it also strongly recommends the use of methane as standard saturation gas when studying the mechanochemical effects of ultrasound.
