X-ray crystallography. Reaction of 4 with AgBF4 and a secondary phosphine or treatment of [Pt(dppe)(COC3F7)(NCMe)][BF4] (5) with a secondary phosphine gives the cations [Pt(dppe)(COC3F7)(PHPhAr)][BF4] (Ar = Mes = 2,4,6-Me3C6H2, 6; Ar = o-anisyl, 7; Ar = Is, 8; Ar = Mes-F9 = 2,4,6-(CF3)3C6H2, 9; Ar = Ph, 10). Deprotonation of the cations with LiN(SiMe3)2 affords the phosphido complexes Pt(dppe)(COC3F7)(PPhAr)
