摘要：

Zeise's anion in strongly basic hydroxylated solvents undergoes unprecedented nucleophilic addition of OR- (R = H, Me, Et) to the eta(2)-ethene giving trans-[PtCl2(eta(1)-C2H4OR)(OR)](2-) which readily reacts with bidentate nitrogen donors N-N to give Cl 2 and OR- substitution and formation of [PtCl(CH2CH2OR)(N-N)]. Protonolysis of this stable organometallic species offers a versatile route to cationic [PtCl(eta(C2H4)-C-2)(N-N)](+) complexes.
