  • Asymmetric Hydrogenation of Dehydroamino Acids and Dehydrodipeptides with Rhodium(I)-modified DIOP Catalysts
    作者:Takamichi Yamagishi、Masanobu Yatagai、Hidetoshi Hatakeyama、Mitsuhiko Hida
    DOI:10.1246/bcsj.57.1897
    日期:1984.7
    the dioxolane ring had a small effect on the asymmetric induction by DIOP in the hydrogenation. Modification at the phosphino group affected the stereocontrol by the ligand and the unsymmetrical DIOP with di-2-naphthylphosphino group gave higher optical yields than (−)-DIOP for the hydrogenation of α-acetamidocinnamic acid and dehydrodipeptides.
    (-)-DIOP 以两种方式进行了修饰:i),在 (-)-DIOP 的二氧戊环上引入了一个大的芳族取代基,以及 ii),用二芳基膦基取代一个二苯基膦基,得到不对称的 DIOP。二氧戊环的修饰对氢化中DIOP的不对称诱导影响很小。膦基的修饰影响了配体的立体控制,并且对于 α-乙酰氨基肉桂酸和脱氢二肽的氢化,具有二-2-萘基膦基的不对称 DIOP 比 (-)-DIOP 产生更高的光学产率。

  • Synthesis of Poly(3-hexylthiophene) by Using the VO(acac)<sub>2</sub>-FeCl<sub>3</sub>-O<sub>2</sub>Catalytic System
    作者:Shuyan Yu、Teruaki Hayakawa、Mitsuru Ueda
    DOI:10.1246/cl.1999.559
    日期:1999.7
    Poly(3-hexylthiophene) (P3HT) was prepared by the oxidation coupling polymerization of 3-hexylthiophene (3HT) with molecular oxygen as an oxidant in the presence of vanadyl acetylacetonate (IV) (VO(acac)2) and ferric chloride (FeCl3). The polymerization at a molar ratio of VO(acac)2 / FeCl3 / 3HT = 1 / 2 / 5 in 1,2-dichloroethane at 0 °C for 164 h under oxygen gave P3HT in 61% yield. The resulting polymer gave a number average molecular weight (Mn) of 2.1 × 104 (Mw / Mn = 3.0; Mw: weight average molecular weight) and a head-to-tail content of 65%. The VO(acac)2-FeCl3 complex is supposed to work as a catalyst.
