Abstract
sigma -Aryl trans-bistriphenylphosphine complexes based on 2,6-di-tert-buty lphenol containing Pt-SnCl3, Pt-GeCl3 groups were synthesized, Oxidation of these compounds gives the corresponding phenoxyl radicals, which were stud ied by ESR spectroscopy, The transformation of the diamagnetic complexes to the paramagnetic state is accompanied by cleavage of the Pt-Sn, Pt-Ge bond s and by elimination of SnCl2, GeCl2.
