Anion catalyzed acid solvolysis of indium(iii) porphyrins

TLDR: For indium(III)-tetrakis-(4-sulfonato-phenyl)porphyrin, the anion effect is in the order Cl−, Br−, SCN− > ClO− 4, BF− 4 and HSO− 4.2.

Abstract: Solvolysis of several water soluble indium(III) porphyrins is catalyzed by both protons and anions. For indium(III)-tetrakis-(4-sulfonato-phenyl)porphyrin, the anion effect is in the order Cl−, Br−, SCN− > ClO− 4, BF− 4, HSO− 4. In HClO4/NaCl, Rate=k(In3+P) (Cl−)2 (ho)2.2
