Y. Maruyama et al., PREPARATION AND PROPERTIES OF 3-ALLYL(HALO)TRIS(TRIMETHYLPHOSPHINE)RUTHENIUM(II) COMPLEXES AND THEIR DERIVATIVES, Chemistry Letters, (6), 1994, pp. 1041-1044
Oxidative addition of allyl halides to Ru(cod)(cot) (cod = 1,5-cyclooc
tadiene, cot = 1,3,5-cyclooctatriene) in the presence of trimethylphos
phine at 50 OC in benzene gives Ru(eta(3)-allyl)(PMe(3))(3)X (X=Br, Cl
), which reacted with PhCHO to yield homoallylic alcohols, and with CO
to afford an eta(2)-acyl complex, RuBr(CO)(PMe(3))(2)(eta(2)-COCH2CH=
CH2), and an (eta(1)-allyl)ruthenium(II) complex, RuBr(CO)(2)(PMe(3))(
2)(eta(1)-allyl).
