The preparation of valuable and industrially relevant organophosphorus compounds currently depends on indirect multistep procedures involving difficult‐to‐handle white phosphorus as a common P atom source. Herein, we report a practical and versatile method for the synthesis of a variety of monophosphorus compounds directly from the bench‐stable allotrope red phosphorus (Pred). The relatively inert Pred was productively functionalised by using the cheap and readily available radical reagent tri‐n‐butyltin hydride, and subsequent treatment with electrophiles yields useful P1 compounds. Remarkably, these transformations require only modest inert‐atmosphere techniques and use only reagents that are inexpensive and commercially available, making this a convenient and practical methodology accessible in most laboratory settings. Valuable, industrially and academically relevant monophosphorus compounds are accessible directly from red phosphorus by using commonly available reagents. Only modest inert‐atmosphere techniques are needed, making this a convenient and practical methodology for the preparation of P1 compounds from elemental, red phosphorus.
