摘要：

Several (eta(3)-allyl)ruthenium(II) complexes bearing carbon monoxide ligands can function as both a nucleophile and an electrophile, i.e., as an ambiphile. Namely, they smoothly react with both aldehydes and NaCH(COOMe)(2) under extremely mild reaction conditions to give the corresponding allylated products in good to high yields. The higher valent (eta(3)-allyl)ruthenium(IV) complex, Cp*RuCl2(eta(3)-allyl) (Cp* = pentamethylcyclopentadienyl), is only electrophilic and unusually high regioselectivity of allylation of carbon and nitrogen nucleophiles can be attained.
