Isolated-palladium complexes for catalyzed telomerization of butadiene with methanol in the presence of water

In order to study the performance of organometallic complexes in the telomerization of butadiene with methanol in aqueous medium, we synthesized and characterised hydrosoluble palladium complexes. [(π-allyl)Pd(TPPTS)2]+Cl− complex exhibited strong stability as no degradation was observed after storage at room temperature under air atmosphere for weeks. TON’s up to 36 000 were achieved at 50 °C.

Cationic hydrosoluble palladium complexes were prepared. They were stable at room temperature under air atmosphere for weeks. They were efficient in the telomerization of butadiene with methanol in the presence of water under mild conditions.Figure optionsDownload as PowerPoint slide
