Chlorophosphaalkenyl- and chloroalkenylstibanes

Mono-, bis- and tris(chlorophosphaalkenyl)stibanes have been obtained from Mes∗PC(SiMe3)Li (Mes∗ = 2,4,6-tri-tert-butylphenyl) or from the phosphaalkene carbenoid Mes∗PC(X)Li (X = Cl) and SbF3, Mes∗Sb(OMes∗)F or Mes∗SbF2. Bis[chloroalkenyl]stibanes [R2CC(Cl)]2SbCl (R2C = fluorenylidene and 2,7-di-tert-butylfluorenylidene) have also been obtained from R2CC(Cl)Li and SbCl3.
