WebTriphenylphosphine undergoes slow oxidation by air to give triphenylphosphine oxide, Ph 3 PO: 2 PPh 3 + O 2 → 2 OPPh 3. This impurity can be removed by recrystallisation of PPh 3 from either hot ethanol or hot isopropanol. This method capitalizes on the fact that OPPh 3 is more polar and hence more soluble in hydroxylic solvents than PPh 3. Webmetric quantity of the phosphine oxide. However, at that time no attempt was made to isolate any intermediates in the reaction. We have now more fully investigated the reaction of [(tBu)~Ga(p-OOtBu)l 2 with phosphines, phos- phites, and triphenylarsine, and the results of this study are presented herein.
