A new base-catalyzed C-alkylation reaction that employs a mixture of n-butyllithium and potassium tert-butoxide in refluxing heptane to produce coal anions that are subsequently treated with n-alkyl halides at 0{degree}C has been developed and applied. Almost quantitative pyridine solubilization was achieved by C-octylation of a Lower Kittanning coal, PSOC 1197. C-Octylation was less successful for the solubilization of bituminous Illinois No. 6 coal, APCSP 3, and subbituminous Wyodak coal, APCSP 2, which gave 35 and 33% soluble material, respectively.
