The Deoxygenation of Sulfoxide Mediated by the Ph3P/Lewis Acid Combination
the Application to the Kinetic Resolution of Racemic Phosphines Using Opti33- 190 and
cally Active Sulfoxide. — The deoxygenation of many kinds of sulfoxides is effectively promoted by the combination of PPh3 and TiCl4 under mild conditions. Racemic
P-chiral and planar-chiral phosphines, and even a phosphine bearing a chiral carbon
center adjacent to the phosphorus are kinetically resolved with moderate enantioselectivities by application of an optically active sulfoxide and TiCl4. — (KIKUCHI, S.;
