Selected model compounds representing coal structural entities were studied under the conditions of HF-BF,H, catalysed mild coal liquefaction. Bibenzyl and diphenylmethane gave near quantitative conversion at room temperature without added hydrogen. Biphenyl, however, required hydrogen pressure at 1
