Is. Cho et H. Alper, PALLADIUM-CATALYZED HYDROGENATION OF ALPHA,BETA-UNSATURATED SULFONES AND PHOSPHONATES, Journal of organic chemistry, 59(15), 1994, pp. 4027-4028
The binuclear palladium complex, [(Bu(2)(t)PH)-PdPBu(2)(t)](2), when t
reated with oxygen, catalyzes the hydrogenation of the double bond of
alpha,beta-unsaturated sulfones and phosphonates in THF at room temper
ature and 1 atm of hydrogen pressure. Saturated sulfones and phosphona
tes were isolated in 49-93% yields.
