Description: Our work on single election transfer in coals led us to the knowledge that the energetics of bond cleavage in radical cations is 20-40 kcal/mole lower than the corresponding homolytic bond cleavage energies. Having made excellent progress in the other areas covered by this proposal, we are extending our studies to the investigation of the formation and cleavage reaction of radical cations in coals. The formation of a radical cation requires the transfer of an electron from a neutral molecule to an appropriate electron acceptor (oxidant). As a first step, we seek oxidants which will form radical cations from functional groups typical of those in coals. We must also study the decomposition behavior of bonds typical of those found in coals. Alkyl and alkoxy aromatic compounds were chosen as the electron donors because of their common occurrence in coals.
