In this paper, the authors report on the reaction of a bituminous coal with a powerful yet selective site-specific reagent, namely, potassium-crown ether operating at room temperature and atmospheric pressure. The potassium-crown ether reagent can generate a stable solution of electrons at room temperature and atmospheric pressure. The small size of the electron and its high reactivity permits it to diffuse into the macromolecular coal network and transfer onto the aromatic substrates in the coal. This results in the formation of aromatic radical anions or dianions which undergo cleavage reactions at ether and diaryl alkane linkages.
