(μ-Tetraphenylporphinato)bis[dicarbonylrhodium(I)], TPP[RhI(CO)2]2, in benzene solutions undergoes photochemical reaction to produce rhodium(II) tetraphenylporphyrin, RhIITPP, which forms its diamagnetic dimer, [RhIITPP]2. The quantum yields of the photoreaction depend strongly on the irradiation wavelengths: Φ ～ 0 at λ > 420 nm, Φ = 0.025 in the range 350 nm a ruby laser and the second (532 nm) and the third (355 nm) harmonics of a Nd-YAG laser revealed that neither the lowest excited singlet nor the triplet state of TPP[RhI(CO)2]2 is concerned with the photochemical reaction. Higher excited singlet states, Sn (probably n > 2), are assumed to be responsible for the reaction. The homolytic cleavage of one of the Rh-N bonds of TPP[RhI(CO)2]2 in Sn is considered to be involved in the reaction pathway.
