The use of microwave irradiation in organic synthesis has become an increasingly popular topic within the pharmaceutical and academic arenas. Microwaves have become a new energy source that is powerful enough to complete reactions in minutes instead of hours, or even days. Currently, the majority of microwave-assisted reactions are performed at high temperatures and pressures. Reactions run at lower temperatures (T < 35 °C) have not yet been fully exploited. There are many applications, both synthetic and biochemical, that require either ambient temperatures or below. Because microwave irradiation is only a source of kinetic energy, lower temperatures are easily attainable through removal of the resulting thermal energy. Herein, we will discuss the methodology and demonstrate the utility of running low-temperature reactions in a microwave.
