1. A compound of the formula:
- ##STR5## wherein M is a transition metal capable of sustaining oxidation, said M being optionally axially ligated to a ligand, each Y and Yo independently H, fluoro or chloro, each R ring is ##STR6## X and Xo are independently H or a non-water solubilizing electronegative group, and X1, X2 and X3 are independently H or an electronegative group, subject to the provisos that;
(1) when none of X1, X2 and X3 is in a water solubilizing group, then at least one of Y and Yo on each porphyrin ring is other than H,(2) when Y and Yo are both H, at least one but not more than two of X1, X2 and X3 is water solubilizing group and at least two of X, Xo, X1, X2 and X3 is a non-water solubilizing electronegative group, or the water soluble salts thereof in which said water solubilizing groups are in corresponding water soluble salt form,(3) no more than two of X1, X2 and X3 is a water solubilizing group,or a compound of the formula I in which the water solubilizing groups are in water soluble salt form.

Abstract
Disclosed are tetraphenyl porphyrins which are beta-substituted by fluoro or chloro and/or bear electronegative substituents on the phenyl including one or two water solubilizing substituents. The new porphorins are particularly suitable as catalysts in a variety of oxidative reactions and methods.
