Reacting white phosphorus (P-4) with sterically encumbered aryl lithium reagents (aryl = 2,6-dimesitylphenyl or 2,4,6-tBu(3)C(6)H(2)) and B(C6F5)(3) gives the unique, isolable Lewis acid stabilized bicyclo[1.1.0]tetraphosphabutane anion. Subsequent alkylation of the nucleophilic site of the RP4 anion gives access to non-symmetrical disubstituted bicyclic tetraphosphorus compounds. This novel method enables P-C bond formation in a controlled fashion using white phosphorus as starting material.
