摘要:
The amination of secondary alcohols to give tertiary amines in the presence of different in situ generated ruthenium catalysts has been investigated in detail. By applying a combination of [Ru-3(CO)(12)] and N-phenyl-2-(dicyclohexylphosphanyl)pyrrole as the catalyst, cyclic amines can be alkylated with different alcohols in high yield, whereas aliphatic amines gave transalkylation side products.
