WebTriphenylphosphine oxide (TPPO) and triphenylphosphine (TPP) can form a complex in solution, promoting visible light absorption to trigger electron transfer within the complex and generate radicals. Subsequent radical reactions with thiols enable desulfurization to produce carbon radicals that react with aryl alkenes to yield new C–C bonds ... WebMay 19, 2024 · Triphenylphosphine oxide (Ph 3 P = O), commonly known as TPPO, is a byproduct of very popular and widely used name reactions such as Mitsunobu, Wittig, …
Triphenylphosphine undergoes slow oxidation by air to give triphenylphosphine oxide, Ph3PO: 2 PPh3 + O2 → 2 OPPh3 This impurity can be removed by recrystallisation of PPh3 from either hot ethanol or isopropanol. This method capitalizes on the fact that OPPh3 is more polar and hence more soluble in polar solvents than PPh3.
