N2 - The transient bicyclo[1.1.0]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 P4derivative. This reaction path enables a simple, stepwise functionalization of white phosphorus. Trap and transfer: The bicyclo[1.1.0]tetraphosphabutane anion (see scheme, center), generated from P4 and Mes∗Li (Mes∗=2,4,6-tBu3C6H2), can be trapped by BPh3 in THF. The anion can be used as an [RP4]- transfer agent, reacting 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 P4 derivative.
