摘要

During UV irradiation of [CpRh(C2H4)(2)] (Cp = eta(5)-C5H5) in hexane/ether in the presence of phenanthrene one ethene ligand is displaced by coordination of the 9,10 double bond of phenanthrene, and (eta(5)-cyclopentadienyl)(eta(2)-ethene)(eta(2)-9,10-phenanthrene)rhodium (1) is formed. The analogous reaction in hexane in the presence of acenaphthylene occurs with formation of the complexes (eta(2)-1,2-acenaphthylene)(eta(5)-cyclopentadienyl)(eta(2)-ethene)rhodium 2 and bis(eta(2)-1,2-acenaphthylene)(eta(5)-cyclopentadienyl)rhodium 3 in which one and two ethene molecules of [CpRh(C2H4)(2)], respectively, are substituted by eta(2)-1,2-acenaphthylene. The irradiation of [CpRh(C2H4)(2)] with triphenylene in hexane yields the compounds [CpRh(eta(4)-1,2,3,4-triphenylene)] (4), [(CpRh)(2)(mu-eta(3):eta(3)-triphenylene)](5), and [(CpRh)(3)(mu(3)-eta(2):eta(2):eta(2)-triphenylene)] (6). Despite the partially very low yields the new complexes could be unequivocally characterized spectroscopically and in the case of 1 and 3 by X-ray structural analysis. The compounds 1 and 2 in solution reveal a novel dynamic behaviour; via an intramolecular C-H activation, exchange occurs between the protons of the eta(2)-coordinated arene and the Cp ligand. The complex 4 in solution is fluxional, too. [References: 24]
