Popis: 1. Paramagnetic Rh(II)O2− and Rh(II)RO2complexes of similar structure are formed in solutions containing triphenylphosphine Rh(I) complexes, both in the presence of O2 and in the presence of a hydroperoxide in an oxygen-free medium. 2. Addition of a hydroperoxide promotes coordination of the Rh(I) compound with both oxygen and RO2.. 3. The Rh(II)RO2 complexes coordinate olefins. 4. The effectiveness of the hydroperoxides in oxidational olefin isomerization can be correlated with the ability to oxidize Rh(I) to Rh(II).
