Triphosphenium Cations

Ph3P=P —PPh3 AlCi + Ph/KHjjjPPhj 2PCI3 + SnClj + 2 Ph2P(CH2)2PPh2 --- [Pg.439]

Reaction (6.784) produces a cation which has equivalent P-P linkages, thus probably indicating resonance as in (6.785ab) with possible contributions from (6.785c). Cyclic cations of similar type are obtained by reactions (6.786,6.787) [26,27,28]. [Pg.439]

The triphosphenium cation produced in Equation 6.789 is reported to form stable salts [29]. [Pg.439]

Phosphinylidene oxophosphoranes and phosphinylidene methylene phosphoranes (Table 6.17) are not as yet well char acterised. An example of the former has been isolated from reaction (6.790) but the compound is readily decomposed by water. [Pg.439]

A phosphinylidene methylenephosphorane (Table 6.17) is reported to be formed in reaction (6.791) but it is poorly characterised. [Pg.439]
