• 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):
• In the presence of TFA, converts epoxides to episulfides (thiiranes) of the same stereochemistry: J. Am. Chem. Soc., 94, 2880 (1972).
