The use of “green chemistry” to obtain ionic liquids by microwave techniques proves to be useful and efficient. The solvent-free route that is obtained by using this technique allows the experiment to reduce the amount of exposure to water as well as shorten the reaction times. The reaction was done in two separate parts to obtain an intermediate compound, which was nbutylpyridinium bromide, and use that compound to isolate and obtain the ionic liquid when reacted in acetonitrile with sodium tetrafluoroborate. The major findings included good yields of the intermediate and final products on a small and large scale. Overall the use of the microwave technique proved to be relatively simple and efficient when obtaining the ionic liquid that could be used to conduct further reactions. More studies have included attempting to use this solvent in homogeneous catalytic hydrogenation reactions and to delineate factors, which challenge this potential application. Further, if successful, this would represent the first ionic liquid used in earth abundant metal hydrogenation catalysis.
