Abstract
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 erved.
