Abstract

The complexes Ru(CO)2C12L [L = 1, 10-phenanthroline (phen) or 2, 2′-bipyridyl (bpy)l react with silver carboxylates to yield Ru(CO)2(OCOR)2L derivatives (R = Me or CF3). Reactions of Ru(CO)2(OAc)2L and Ru(CO)2(OAc)2(phen) with trifluoroacetic and trifluoromethanesulfonic acid give Ru(CO)2(OCOCF3)2L and Ru(CO)2(OSO2CF3)2(phen) respectively. In acetonitrile, Ru(CO)2(OAc)2L complexes react with trifluoromethanesulfonic acid to give [Ru(CO)2(MeCN)2L] (O3SCF3)2. The complexes [Ru(CO)2L2]2+, [Ru(CO)2(phen)(bpy)]2+, and [Ru(CO)2(phen)(tmp)]2+ (tmp = 3, 4, 7, 8-tetramethyl-l, 10-phenanthroline) have been prepared by reaction of [Ru(CO)2- (MeCN)2L]2+ and/or Ru(CO)2(OSO2CF3)2phen with an excess of the appropriate bidentate ligand. A similar series of reactions has yielded Ru(CO)2(OAc)2(py)2, [Ru(CO)2(MeCN)2(py)2] (O3SCF3)2, and [Ru(CO)2(py)2L]2+ from Ru(CO)2Cl2(py)2. Stereochemical assignments have been made for all complexes.
