^aSee Supporting Information for full experimental details. Yields for P, B, and Ph-H are corrected vs internal standard (dodecane). Yields of E are uncorrected.

^b>50% of both enone and PhI remained.

^c>10% of both enone and PhI remained.

^dReaction run with 10 mol % [Ni] and L1 in DMF.

^e>10% of enone remained.

^f>10% of PhI remained.
