Recent advances on iron-catalyzed coupling reactions involving organolithium reagents

Owing to their inexpensive and environmentally friendly properties, iron-based catalysts have been actively investigated for new organic reactions. In this account, we summarized our recent results on iron-catalyzed cross-coupling reactions and homo-coupling reactions. With iron-based catalysts, we constructed diverse carbon-carbon bonds, i.e., C(sp²)-C(sp³), C(sp³)-C(sp³), C(sp³)-C(sp²) and C(sp²)-C(sp²) bonds. In order to demonstrate the usefulness of our iron protocol, we also carried out these reactions on gram-scale reactions, leading to good yields
