The rearrangement of the molecular ions of the isomeric 2-and fmethyl benzofurans (1 and 2), 2H-chromene (3) and 4H-chromene (4) has been studied as a further example of the isomerization of oxygen-heteroaromatic radical cations via a ring expansionlring contraction mechanism well documented for mol
