A novel ruthenium carbene dimer that is active in the metathesis of internal alkenes; the crystal structure of Ru-2(=CHPh)(2)(CF3CO2)(2)(mu-CF3CO2)(2)(PCy3)(2)(mu-H2O)
W. Buchowicz et al., A novel ruthenium carbene dimer that is active in the metathesis of internal alkenes; the crystal structure of Ru-2(=CHPh)(2)(CF3CO2)(2)(mu-CF3CO2)(2)(PCy3)(2)(mu-H2O), J ORGMET CH, 588(2), 1999, pp. 205-210
The reaction of Ru(=CHPh)Cl-2(PCy3)(2) (1) with two equivalents of CF3CO2Ag
gives Ru-2(=CHPh)(2)(CF3CO2)(2)(mu-CF3CO2)(2)(PCy3)(2)(mu-H2O) (2) in high
yield. The crystal structure of 2 reveals that the ruthenium atoms are bri
dged by two trifluoroacetate groups and one water molecule, and that the ru
thenium coordination is distorted octahedral. Complex 2 is active in the me
tathesis of internal alkenes. (C) 1999 Elsevier Science S.A. All rights res
