Pentamethylcyclopentadienyl ruthenium : an efficient catalyst for the redox isomerization of functionalized allylic alcohols into carbonyl compounds

Abstract The catalytic activity of the ruthenium(II) complex [RuCp ∗ (CH 3 CN) 3 ][PF 6 ] 1 in the transposition of allylic alcohols into carbonyl compounds, in acetonitrile, is reported. This catalyst has proven to be able to catalyze the transformation of poorly reactive and/or functionalized substrates under smooth conditions.
