Sodium exhibits better efficacy and selectivity than Li and K for converting Ph3P(O) to Ph2P(OM). The destiny of PhNa co-generated is disclosed. A series of alkyl halides R4X and aryl halides ArX all react with Ph2P(ONa) to produce the corresponding phosphine oxides in good to excellent yields.

Phosphorus yldes based on the dibenzophosphole (DPP) ring system convert aldehydes into trans-disubstituted oxaphosphetanes with good to excellent selectivity.Decomposition at 70-110 deg C affords alkenes with E:Z rations from 6:1 to > 100:1.
