  Photochemical C–H bond activation of diruthenium bridging alkylidene complexes: Interligand H-exchange on Cp2Ru2(μ-CH2)(μ-CHR)(CO)2 (R=H, Me)

  摘要：

  Irradiation of a double labeled diruthenium di-mu -methylene complex, Cp2Ru2(mu -CH2)(mu-*CD2)(CO)(2) (5-C-13,d(2)) (*C: C-13-enriched), caused H-D exchange between the two bridging methylene ligands to give an isomeric mixture of Cp2Ru2(mu -CHD)(mu-*CDH)(CO)(2) and Cp2Ru2(mu -CD2)(mu-*CH2)(CO)(2). In contrast to the photochemical hydrogen migration of 5-C-13,d(2), irradiation of a deuterated mu -methylene-mu -ethylidene complex, Cp2Ru2(mu -CD2)(mu -CHCH3)(CO)(2) (7-d(2)), resulted in interligand exchange between beta -hydrogen atoms of the ethylidene ligand and methylene hydrogen atoms to afford a mixture of Cp2Ru2(mu -CHD)(mu -CHCH2D)(CO)(2) and Cp2Ru2(mu -CH2)(mu -CHCHD2)(CO)(2). These exchange reactions can be interpreted in terms of mu -methylidyne, CpRu(Co)(mu -CH)(mu -CH2)Ru(H) Cp, and mu -alkenyl intermediates, CpRu(CO)(mu -CH)(mu -CH=CH2)Ru(H)Cp, respectively. These species may be formed photochemical decarbonylation followed by migration of alpha- and beta -hydrogen atoms of the bridging ligands to the coordinatively unsaturated ruthenium center. Subsequent CH2-H reductive elimination and free rotation of the resulting Ru-CH3 bond would cause the interligand H-exchange. Similar processes may be viable on a heterogeneous catalyst surface.
