solvents as sustainable reaction media, at roomtemperature and in the absence of protecting atmosphere, through direct deprotonation of both aliphatic and aromatic secondary phosphines (HPR2) by n‐BuLi. The subsequent addition of in‐situ generated LiPR2 to aldehydes or epoxides proceeded quickly and chemoselectively, thereby allowing the straightforward access to the corresponding α‐ or β‐hydroxy phosphine

bonds via the iron-catalyzed phosphorylation of alcohols under ligand-free conditions is disclosed. This strategy represents a straightforward process to prepare a series of phosphine oxides and phosphine compounds in good to excellent yields from the readily available alcohols and P–H compounds. A plausible mechanism is also proposed. We anticipate that this mode of transforming simple alcohols would
