The Iron Catalyzed Reaction between Nitrosyl Disulfonate and Hydroxylamine Monosulfonate Ions [PDF]

open access: yes, 1953
Potassium nitrosyl disulfonate, K2NO(SO3)2, is noteworthy because the solid salt is orange in color and diamagnetic while its neutral aqueous solutions are purple in color and paramagnetic.

On a dynamic reaction-diffusion mechanism: The spatial patterning of teeth primordia in the alligator [PDF]

open access: yes, 1996
It is now well established both theoretically and, more recently, experimentally, that steady-state spatial chemical concentration patterns can be formed by a number of specific reaction–diffusion systems.
