A new and selective one-step synthesis was developed for the first activation stage of white phosphorus by organic radicals. The reactions of NaCpR with P-4 in the presence of CuX or FeBr3 leads to the clean formation of organic substituted P-4 butterfly compounds (Cp2P4)-P-R (Cp-R: Cp-BIG = C-5(4-nBuC(6)H(4))(5) (1a), Cp"' = C(5)H(2)tBu(3) (1b), Cp* = C5Me5 (1c) und Cp-4iPr = C(5)HiPr(4) (1d)). The reaction proceeds via the activation of P-4 by Cp-R radicals mediated by transition metals. The newly formed organic derivatives of P-4 have been comprehensively characterized by NMR spectroscopy and X-ray crystallography.
