The development of efficient transformations of abundant functional groups has been a central topic in synthetic organic chemistry. For example, among the numerous C-C bond formations, transition metal-catalyzed cross-coupling reactions are generally the most reliable and indispensable. On the one hand, these cross-coupling reactions generally require the use of halogenated substrates and a two-step process involving a halogenation step and C-C bond formation. Hydroxyl group is one of the most abundant functional groups, and several efficient conversion reactions have recently been reported (Figure ). In 2018 and 2022, Suga, Ukaji et al. reported direct conversion reactions of alcohols using This reaction is applicable to primary to tertiary alcohols and proved to be useful because it can be used for aliphatic alcohols. In 2020, Wang, Shu et al. reported the first C-O bond cleavage of tertiary alcohols using Cp*TiCl3 as a catalyst. In the meantime, the development of sustainable chemical reactions with less waste using photoredox chemistry 5 and electrochemistry has gained momentum recently. In 2021, Li et al. reported nickel-catalyzed dehydroxylative cross-coupling using electrochemistry. This reaction is an excellent way to directly form C(sp 2 )-C(sp 3 ) bonds from primary and secondary alcohols. From 2021 to 2023, MacMillan et al. reported a direct alcohol conversion reaction using NHC, photoredox catalyst, Ni-or Fe-catalyst. 9 This reaction is applicable from primary to tertiary alcohols. Iron is abundant, inexpensive, non-toxic, and has been used for a long time. Even in recent years, some Fe-catalyzed organic chemical reactions have been reported. 10 However, the catalytic use of iron in organic chemistry is less common than that of other transition metals such as Pd-, Ni-, and Co-catalyst. In this context, we report the direct C-C bond formation reaction using a redox-neutral Fe-electrocatalytic deoxygenative Giese reaction.
