Pentamethylcyclopentadienyl-rhodium and -iridium complexes. Part 31. Tri-µ-phenoxo-rhodium complexes and a facile H/D exchange reaction
Abstract
[{Rh(C5Me5)}2(OH)3][PF6] reacts with phenol to give [{Rh(C5Me5)}2(OPh)3][PF6](3), containing three µ-phenoxo-ligands. The related complexes [{Rh(C5Me5)}2(OH)3]X (X = Cl or OH) react with phenol to give [{Rh(C5Me5)(OPh)2(PhOH)2}n] which is formulated as the tri-µ-phenoxo-complex [{Rh(C5Me5)}2(OPh)3]-[(PhO)5H4](4), largely on the basis of the 13C n.m.r. spectra. The methyl hydrogens in (4)[but not in (3)] exchange very rapidly for deuterium in [2H6] acetone solution.
