Applications

Triphenylphosphine sulfide involves in the , conversion of epoxides to episulfides (thiiranes) in presence of TFA of the same stereochemistry. It acts as a ligand for the Pd-catalyzed bisalkoxycarbonylation of olefins.

Notes

Store in a cool, dry, conditions in well sealed container. Store away from oxidizing agents.

The Pd-catalyzed bisalkoxycarbonylation of olefins gives improved yields in the presence of triphenylphosphine sulfide as a ligand. The phosphine oxide and selenide were significantly less effective, and no product was obtained with triphenylphosphine itself: Tetrahedron Lett, 39, 7529 (1998):
