| Research Abstract |
Diphenylphosphine oxide and related P(0)-H compounds react with propargyl alcohols at room temperature in the presence of a catalytic amount of Ni(0) complex and Ph2P(0)OH to produce high yields of phosphinoyl 1,3-dienes though an efficient in situ dehydration process. On the other hand, by using Josiphos ligands, palladium-catalyzed hydrophosphorylation of norbornenes with hydrogen phosphonates proceeded efficiently to give the corresponding phosphonates in high enantioselectivities. More over, a variety of functionalized optically pure (RP)-alkylphenylphosphinates are readily prepared by stereospecific radical or base-catalyzed additions of the easily available (RP)-menthyl phenylphosphinate to alkenes.
