Fig. 3. Substrate scope.

Reaction conditions: 1 or 5 (0.1 mmol), 2 (0.2 mmol), NiCl₂(DME) (10 mol%), L8 (30 mol%), Cs₂CO₃ (0.2 mmol) and (EtO)₂MeSiH (0.3 mmol) in THF/DMA = 9:1 (0.5 mL) at 40 °C under Ar for 18 h. cis-Alkenes were used if not denoted otherwise. Yields of isolated γ-product. Isomeric ratios (γ:β) were determined by ¹H NMR analysis of the crude mixture (>20:1 rr if not denoted otherwise). ^a2 (2.5 equiv) was used at 60 °C. ^bNiCl₂(DME), 2 and (EtO)₂MeSiH were added at 60 °C in two batches of 5 mol%, 1.25 equiv and 1.5 equiv, respectively.
