Unexpected Structure of Palladacycles Containing Carboxylated Schiff Bases. Synthesis of Some Water-Soluble Metallacycles
摘要:
The action of palladium acetate on carboxylated Schiff bases is herein described. These reactions lead to new metallacycles, some of which are hydrosoluble. Additionally we present the first report of cyclopalladated derivatives having the metalated molecule as a dianionic (C,N,O) bridging ligand between two palladium atoms.
