Abstract: | The photochemical rearrangement of Rh(η4-1,5-cod)TpMe2](TpMe2=hydrotris(3,5-dimethylpyrazolyl)borato, 1,5-cod=cycloocta-1,5-diene) to the new compound Rh(η4-1,3-cod)TpMe2] ( 2 ) is described. The characterization of 2 was carried out using 1H-, 13C-, and 103Rh-HMQC-NMR spectroscopy. Photolysis of 2 is a versatile entry point into the organometallic chemistry of the {RhTpMe2} fragment as it can be used to produce a) hydrido-carbonyl (Rh(CO)H2TpMe2]), b) hydrido-phenyl-phosphite (RhH(Ph)(P(OMe)3)TpMe2]), and c) ethoxide-hydrido-phosphite (RhH(OEt)(P(OMe)3)TpMe2]) complexes. |
