Ruthenium trichloride, in preparation of ruthenocene

Ruthenocene has been prepared in 20% yields by reaction of cyclopentadienylmagnesium bromide with ruthenium(III) acetyl-acetonate.8 More recently,4 the compound has been made in 43-52% yield by treatment of sodium cyclopentadienide with ruthenium trichloride in tetrahydrofuran or 1,2-dimethoxyethane. [Pg.50]

Unsymmetrically substituted ruthenocenes may also be prepared using gas-phase electrocyclic reactions of penta-dienylruthenium complexes. The precursor compounds are obtained by zinc reduction of either ruthenium trichloride in the presence of 5,5-dimethylcyclohexadiene to give bis(6,6-dimethylcyclohexadienyl)ruthenium or Cp RuClala in the presence of 2,4-di-/l r -butyl-l,3-pentadiene to give (pentamethylcyclopentadienyl)(2,4-di-/ r7-butylpentadienyl)ruthenium or dimethylcyclohexadiene to give (pentamethylcyclopentadienyl)(6,6-dimethylcyclo-hexadienyl)ruthenium. Sublimation of these compounds at 400-450 °C afforded the ruthenocenes 6-8. ... [Pg.632]
