  Significance of Carbenoid Character during the Protonation of Four- and Five-Membered Diruthenacycles Formed from the Reaction of Ru2(Me2PCH2PMe2)2(CO)5 with Dimethyl Acetylenedicarboxylate

  摘要：

  Protonation of the diruthenacyclobutene Ru-2(dmpm)2(CO)(4)[mu-eta(1):eta(1)-C-2(CO(2)Me)(2)] (dmpm = bis(dimethylphosphino)methane) resulted in stereoselective formation of the chelated (Z)alkenyl complex {Ru-2(dmpm)(2)(CO)(4)[C-2(H)(CO(2)Me)(2)]}[BF4], as deternnined by single-crystal X-ray crystallography (P2(1)2(1)2 (No. 18) space group, a = 15.61(2) Angstrom, b = 22.67(2) Angstrom, c = 9.34(1) Angstrom, V = 3308(5) Angstrom(3), Z = 4). Protonation of the diruthenacyclopentenone Ru-2(dmpm)(2)(CO)(4) [mu-C(O)C-2(CO(2)Me)(2)] occurs reversibly at the carbonyl oxygen of the bridging group, giving the corresponding diruthenacyclopentenol. The X-ray crystal structure of the solvated molecule [P2(1) (No. 4) space group, a = 16.010(7) Angstrom, b = 11.833(6) Angstrom, c = 19.450(8) Angstrom, beta = 103.44(3)degrees, V = 3584(5) Angstrom(3), Z = 4) and its unusual blue color suggest a highly delocalized pi-system between the two metals. Reaction of the metal hydride [HRu2(dmpm)(2)-(CO)(5)][BF4] with dimethyl acetylenedicarboxylate (DMAD) results in formation of a new C-H bond and a sigma-bound (E)-alkenyl ligand. This same (E)-alkenyl product can also be formed by addition of CO to and alkene isomerization of the chelated (Z)-alkenyl complex{Ru-2(dmpm)(2)(CO)(4)[C-2(H)(CO(2)Me)(2)]}[BF4].
