Free radicals formed in the reaction of 1H-1-oxo-2,4,6,8-tetrakis(tert-butyl)phenoxazine and 1-hydroxy-2,4,6,8-tetrakis(tert-butyl)phenoxazinyl radical with certain organometallic compounds

1H-1-Oxo-2,4,6,8-tetrakis(tert-butyl)phenoxazine undergoes ligand exchange reactions and behaves as a spin trap for metal-centered radicals, as a result of which stable paramagnetic complexes are formed with delocalization of the unpaired electron in the organic ligand.
Paramagnetic complexes are also formed as the result of a reaction between potassium salt (IA) and triphenyl-tin and triphenyl-lead monochlorides.
