Abstract
The photochemical rearrangement of [Rh(eta(4)-1,5-cod)Tp(Me2)](Tp(Me2) = hydrotris(3,5-dimethylpyrazolyl)-borato, 1,5-cod = cycloocta-1,5-diene) to the new compound [Rh(eta(4)-1,3-cod)Tp(Me2)] (2) is described. The characterization of 2 was carried out using H-1-, C-13-, and Rh-103-HMQ - NMRspectroscopy. Photolysis of 2 is a versatile entry point into the organometallic chemistry of the {RhTp(Me2)} fragment as it can be used to produce a) hydrido-carbonyl ([Rh(CO)H(2)Tp(Me2)]), b) hydrido-phenyl-phosphite ([RhH(Ph)(P(OMe)(3))Tp(Me2)]), and c) ethoxide-hydrido-phosphite ([RhH(OEt)(P(OMe)(3))Tp(Me2)]) complexes.File in questo prodotto:
