Phosphinidenes [R‐P] are convenient P1 building blocks for the synthesis of a plethora of organophosphorus compounds. Thus far, transition‐metal‐complexed phosphinidenes have been used for their singlet ground‐state reactivity to promote selective addition and insertion reactions. One disadvantage of this approach is that after transfer of the P1 moiety to the substrate, a challenging demetallation
