The reactions of methylenediphosphanes 1a-c with hexafluoroacetone (HFA) and hexafluorothioacetone dimer (HFTA) gave the respective carbodiphosphoranes 5a, 5b, 6, 15, and 19. The carbodiphosphoranes 6 and 19, with phenyl groups at phosphorus, were able to react further with C=O or C=S functions. Compound 6 added one equivalent of HFA across one of the ylidic P=C bonds to give compound 9, a stable intermediate of the Wittig reaction. The addition of HFTA to 19 gave, unexpectedly, the isomeric compound 21. The molecular structures of 9, 15, and 21 were confirmed by X-ray investigations.
