The chemical structure'' of coal, if indeed there is one, remains an enigma. Over the years numerous chemists have integrated a host of experimental observations to generate various average'' structures which differ greatly. Our approach is to regard the structural question of coal as a problem in natural product chemistry. Our model is that of a macromolecular polymer initially synthesized from monomeric naturally-occuring hydroxy and methoxy substituted propenylbenzenes (C{sub 6}-C{sub 3} units), properly aligned to undergo oligomerization reactions via conventional organic reaction mechanisms, specifically Diels-Alder radical cation condensations, phenolic coupling, and proton-catalyzed isomerization and cyclization.
