[a]

GC calibrated yield.

[b]

General conditions: substrate (1 equiv), [Ph2I]OTf (2 equiv), Pd(NO3)2 (0.10 equiv), Ir(ppy)2(dtbbpy)PF6 (0.05 equiv), MeOH (0.2 M in substrate), 26 W lightbulb, 15 h, r.t., degassed by sparging with N2.

[c]

General conditions: substrate (1 equiv), [PhN2]BF4 (4 equiv), Pd(OAc)2 (0.10 equiv), Ru(bpy)3Cl2•6H2O (0.025 equiv), MeOH (0.1 M in substrate), 26 W lightbulb, r.t., 15 h, degassed by sparging with N2.

[d]

[Ph2I]BF4 was the oxidant.

[e]

Product 17a was not detected by GC, and only traces amounts of 17 and 3′-methylacetophenone were formed.
