| Abstract: | Pd(OAc)2(palladium acetate)/(S)-P-PHOS((S)-2,2',6,6'-tetramethoxy-4,4'-bis(diphenyl)phosphino)-3,3'-bipyridine) catalysis systems were applied to the alternating copolymerization of propene and CO in organic solvents to synthesize chiral polyketones.The di-astereoselective reduction of a chiral polyketone using excess LiAlH4(lithium aluminum hydride) and NaBH4(sodium borohydride) as reducing agents gave a new class of optically active polyalcohol and the product yield was more than 90%.In the presence of va... |
