A Colorado subbituminous coal was reacted with potassium and naphthalene in tetrahydrofuran. This was then alkylated with n-butyl iodide and the solubility in tetrahydrofuran was determined. The solubility was found to be less than in a corresponding reaction with Illinois No. 6 coal. The solubilization of a Colorado subbituminous coal by reacting it with potassium in liquid ammonia, followed by alkylation is discussed. The preliminary results from a reaction of Illinois No. 6 coal with tetrabutylammonium hydroxide and methyl iodide are reported. Reductive acylation of coal is being studied at the present time using trifluoroacetic anhydride as a quenching reagent. /sup 19/F is a candidate for nmr studies and chemical shifts for trifluoroacetyl derivatives of phenols, thiols, and amides indicate that fluorine may be useful as a sensitive probe for reactive species in coal. The effort on donor solvent coal chemistry was directed to the role played by pericyclic reactions in the liquefaction process. The acceptors were reduced by the deuterated donors. The isotopic distribution of the reduction product indicates that free radical processes occur preferentially. Thus, the pericyclic reactions appear to be unimportant at the threshold reaction temperatures of 350 to 425/sup 0/C. The reactions of aromatic ethers with inorganic sulfide at 400/sup 0/C produces thiophenols.
