Solvated electrons prepared by dissolution of alkali metals in ethers can be transferred to coal. Subsequent hydrolysis with a mild proton donor yields coal derivatives which are up to 85% extractible by pyridine and have a H/C-ratio of 41.4.

Chemical structures of four Turkish coals in original and reductively alkylated forms were investigated in the solid state by CP/MAS ' 3C n.m.r. and i.r. spectroscopies. Dilatation properties of these samples were also determined. It was observed that, while the aliphatic parts of the coking coals a
