Description

The interaction between diarylmagnesiums, MgAr2(Ar = C6H5, 2-MeOC6H4 and 4-FC6H4) and the metal-metal bonded binuclear bridged tetra-acetates, M2sup(II)(CO2Me)4, (M = Mo and Rh) and Rusup(II,III)(CO2Me)4Cl in the presence of trimethylphosphine produces monomeric (Ru,Rh) or dimeric (Mo)aryls; for Ru and the 2-methoxyphenyl, hydrogen loss from the MeO group leads to formation of a metallocycle. In the absence of PMe3, Re2(O2CMe)4Cl2 gives a dimeric binary aryl, Re2(2-MeOC6H4)6. The compounds have been studied by 1H, 31P, and 13C n.m.r. and i.r. spectroscopy. Likely structures are discussed.
