On the carbon nucleophilicity of proton sponge
Abstract
Proton sponge [1,8-bis(dimethylamino)naphthalene] acts as a carbon nucleophile towards co-ordinated alkenes in [Pt(η2-alkene)Cl(Me2NCH2CH2NMe2)]+(alkene = ethylene, propene or styrene), the resulting Pt–C σ bond being cleaved by acids to afford the 4-alkyl-substituted base.
