| Abstract: | The transient bicyclo1.1.0]tetraphosphabutane anion, generated from white phosphorus (P4) and Mes*Li (Mes*=2,4,6‐tBu3C6H2), can be trapped by BPh3 in THF. This Lewis acid stabilized anion can be used as an RP4]? transfer agent, reacting cleanly with neutral Lewis acids (B(C6F5)3, BH3, and W(CO)5) to afford unique singly and doubly coordinated butterfly anions, and with the trityl cation to form a neutral, nonsymmetrical, all‐carbon‐substituted P4 derivative. This reaction path enables a simple, stepwise functionalization of white phosphorus. |
