^aStandard conditions (see Supporting Information): Reactions were run with 0.5 mmol 1-octene, 1.0 mmol tert-butyl isocyanate, 0.05 mmol

Ni(cod)₂, and 0.05 mmol IPr in 0.5 mL toluene under Ar(g) in a sealed

tube at 60 °C for 18–24 h.

^bIsolated yields.

^cReaction was run using 2 mL toluene.

^dIsolated as a mixture of 8b and 8c, with relative ratios determined by ¹H NMR.
