Benzyl phosphonium ions prepared

Benzyl phosphonium ions, polymer-bound, alkenes prepared, l65t Benzyne... 

Reactions of benzylic phosphonium salts were carried out at 20 °C using 10 mL of methylene chloride, 1.5 mmol of the polymeric phosphonium salt, and 3 mL of 50% NaOH (aq). The linear polystyrene had a MW of 150,000 with 2.7 mmol of -PPh2/g of polymer. The cross-linked polystyrene contained 3.0-3.5 mmol of -PPh2/g of polymer. The halogenated phosphonium ion was prepared from phos-phinated polystyrene having 0.4 mequiv of -PPh2/g of polymer and was allowed to react with para-tolualdehyde at 50 C for 16 h.
