The goal of an oxidation may end on various stages. Does your institution subscribe to Scifinder or Reaxys? There you can enter both your educt Ph3P and the desired product and you're quite safe the results will be in decent journals.

Triphenylphosphine (PPh₃) can be oxidized to triphenylphosphine oxide (Ph₃PO) by reacting it with oxygen in the air. The reaction proceeds slowly and can be represented as:

2PPh₃+O₂→2Ph3PO2PPh + O₂ → 2Ph₃PO

This oxidation process is often used to purify triphenylphosphine, as the oxide can be easily removed by recrystallization

In a common oxidation reaction, triphenylphosphine reacts with hydrogen peroxide to form triphenylphosphine oxide (Ph3PO). The reaction equation is: P(Ph)3 + H2O2 = O=P(Ph)3 + H2O‌
