Catalytic Pd(OAc)2 and polymethylhydrosiloxane (PMHS), in conjunction with aqueous KF, and a catalytic amount of an aromaticchloride, effects the chemo-, regio-, and stereoselective deoxygenation of benzylic oxygenated substrates at room temperature in THF. Preliminary mechanistic experiments suggest the process to involve palladium−nanoparticle-catalyzed hydrosilylation followed by C−O reduction
Thioethers bearing an optically active secondary alcohol were desulfurized with Raneynickel — sodium hypophosphite — acetate buffer system to give optically active alcohols without racemization in high yields. This Raneynickel combination system exhibited a unique desulfurization of benzylthio or phenylthio group in the presence of benzyl ether.
