Pd-Boron-Catalyzed One Carbon Isomerization of Olefins: Water Assisted Process at Room Temperature

A palladium boronate/borane-system -catalyzed isomerization of olefins has been uncovered. An efficient Cy2 FG catalytic combination of [Pd(OAc)(2)](3)-boronate-PCy3-enabled olefin isomerization at 80 degrees C has been investigated. Addition of water to the reaction showed a remarkable improvement and the isomerization occurred at ambient temperature. These catalytic systems function efficiently for the isomerization of functionalized as well as unfunctionalized olefms. The catalytic conditions demonstrate the involvement of both nonhydride and metal-hydride medium and can be switchable with water as an additive.
