Bis(triphenylphosphine)palladium(II) chloride (15.2% …
classified as an irritant upon acute exposure and a neurological hazard upon chronic exposure. It is incompatible with strong oxidizing agents. Arylphosphines are less reactive toward molecular oxygen than benzyl- or alkylphosphines, but air oxidation of triphenylphosphine nonetheless occurs to an appreciable extent, particularly in solution, to give triphenylphosphine oxide. Triphenylphosphine has low fire and explosion hazards, but, when heated to decomposition, it emits highly toxic fumes of phosphine and PO. Use in a fume hood.
Triphenylphosphine oxide - Revolvy
It is also used for the decomposition of organic s to ketones and aldehydes, although is more popular for the reaction as the side product, is more readily separated from the reaction mixture than triphenylphosphine oxide. Aromatic are reduced to the corresponding amine in high yield at room temperature with irradiation:

bis triphenylphosphine palladium ii chloride
Triphenylphosphine binds well to most , especially those in the middle and late transition metals of groups 7–10. In terms of steric bulk, PPh3 has a of 145°, which is intermediate between those of P(C6H11)3 (170°) and P(CH3)3 (115°). In an early application in , NiBr2(PPh3)2 was used by for the synthesis of acrylate esters from , , and . 's further popularized the use of PPh3, including the then revolutionary catalyst RhH(PPh3)2(CO)2.
