In a glovebox, an oven dried screw-capped 2 mL vial was charged with [(η6 -C6H6)Ni( Me IPr tBu )] (10 μmol), degassed (free pump thaw) toluene (0.1 mL) was then added. ketone D-1i (0.1 mmol), and olefin 2d (0.2 mmol degassed by freeze pump thaw) was added successively. The vial was sealed with a Teflon-lined screw cap, and running inside the glovebox at 40 o C. After 72 h, the vial was shipped outside of the glovebox. The reaction mixture was diluted with dichloromethane and filtered through a plug of silica gel. The crude solution was concentrated in vacuum and subjected to column chromatography 100:1 PE/EA to isolate the products, the isolated olefin isomers shown below matched the reported structure .
