英文摘要	[Ru(eta(5)-C(5)Me(4)R)(MeCN)(3)][PF(6)] (R = CH(2)tBu, iPr, tBu, and CF(3); 2-5) complexes were synthesized in two steps starting from the appropriate cyclopentadienes and RuCl(3)center dot 3H(2)O. The fully substituted ruthenocenes [Ru(C(5)Me(5))(C(5)Me(4)R)], [Ru(C(5)Me(5))(C(5)nPr(4)R)] {R* = (lR,5S)-6,6-dimethylbicyclo[3.1.1]hept-2-en-2-yl} and [Ru(C(5)Me(5))(C(5)nPr(5))] were obtained by treating [Ru(C(5)Me(5))Cl](4) with the corresponding cyclopentadienyllithiurn salts. Complexes 2-5 were evaluated as catalyst precursors for nucleophilic allylic substitution reactions, and the results were compared to those obtained with the [Ru(C(5)Me(5))(MeCN)(3)][PF(6)] (1) precatalyst. The etherification of p-methoxyphenol with the typical aliphatic chlorohexene allylic substrate shows that the introduction of the bulky tert-butyl and trifluoromethyl groups into the tetramethylcyclopentadienyl ring results in a valuable enhancement in regioselectivity in favour of the branched allyl aryl ether.
