Synthesis | Gas Loading | Inert Gas Atmosphere in Microwave Reactions
Microwave synthesis is not limited to reactions in air. Flushing reaction mixtures with inert gas, i.e. nitrogen or argon, can be easily done to successfully perform reactions in inert atmosphere. Furthermore, even gaseous reagents can be loaded into microwave vessels for respective transformations.
The use of microwave reactors for chemical reactions has been a success story of many years. Due to obvious reasons, such as the impressive reduction of reaction times and by-products as well as the convenient and safe handling under elevated pressure/temperature conditions, meanwhile almost any type of reaction has already been performed under microwave irradiation.
Besides common reactions, which tolerate the presence of air, there are also many transformations in organic synthesis, polymer chemistry or nanoscience, which require inert gas atmosphere due to the application of air sensitive starting materials, reagents and/or products.
Herein it is shown that it is easily possible to create inert gas atmospheres in monomode reactors as well as in multimode instruments.
