spectroscopy is capable of distinguishing axial and equatorial substitution in trigonalbipyramidaltrifluoromethylphosphoranes allowing the establishment of a partial ‘apicophilicity’ series for somesubstituentgroups which appears to be based chiefly on inductive rather than mesomeric or electronegative parameters of the groups.

Direct combination of (CF3)3PO with hexamethyldisiloxane yields the new phosphorane (CF3)3P(OSiMe3)2 which thermally decomposes to (CF3)2P(O)OSiMe3; the latter new compound can also be obtained by reaction of (CF3)2P(O)Cl with hexamethyldisiloxane.
