Scheme 30.

Scheme 30.

(A) The original mechanism proposed for nickel metallaphotoredox-catalyzed C–N cross coupling. (B) An alternate C–N cross coupling mechanism for aniline substrates proposed by Oderinde. (C) Current revised mechanism for nickel metallaphotoredox-catalyzed C–N cross coupling. Note: blue SET boxes represent a specific coupled electron transfer even between IrIII* and organometallic intermediate 30.2.
