	abstract = {The synthesis of symmetrical porphyrins chlorinated at both ortho positions of the meso-aryl substituents, and the chlorination and bromination of the beta-pyrrole positions is reported. The beta-chlorination of meso-tetraphenylporphyrin via its nickel(II) complex is also described. In addition, we communicate the first perchlorination of tetramesitylporphyrin, where halogen substitution occurred at the beta-pyrrolic positions as well as at both the vacant meta positions of the trimethylphenyl groups. The iron complexes of these various polyhalogenated porphyrins are also described, since they are robust and efficient catalysts in oxidation reactions.},

	abstract = {{Aqueous chlorination of 4-methyltrichlorocatechol 2 gave the tetrachlorohydroxycyclohexenone 4, which crystallized as the hydrate 5. Reaction of 4 with aqueous sodium hydroxide resulted in a benzilic acid rearrangement to the tetrachlorodihydroxycyclopentenecarboxylic acid 6. These reactions have important implications with respect to understanding how lignin is removed during pulp bleaching. Crystals of the tetrachlorotrihydroxycyclohexenone 5 are monoclinic},
