  Synthese funktionalisierter tipod-Liganden: Aufbau, Veresterung und Koordinationsfähigkeit von HOCH2C (CH2PPh2)3

  摘要：

  Starting from pentaerythritol, HOCH2C(CH2OH)3, the synthesis of the hydroxy functionalized tripod-ligand HOCH2C(CH2PPh2)3, 4, is achieved in a few steps. Esterification of the hydroxy group of 4 opens a route to the convergent construction of functionalized tripod-ligands R'COOCH2aCH2PR2)3. For ligand 4 and for its benzoyl derivative PhCOOCH2C(CH2PPh2)3, 6, the capability of forming facially coordinated tripod-complexes is verified by the formation of molybdenum and cobalt complexes. The results are documented by the usual analytical techniques as well as by X-ray analyses.

• Synthesis of the first polymer-supported tripodal triphosphine ligand and its application in the heterogeneous hydrogenolysis of benzo[b]thiophene by rhodium catalysis

  日期：——

  A p-styrenyl substituent attached to the ligand framework allows the tripodal triphosphine moiety –C(CH2PPh2)3 to be introduced as a pendant group in polystyrene matrices via free-radical copolymerisation; in conjunction with rhodium(I), the polytriphos material forms an effective heterogeneous catalyst for the hydrogenolysis of benzo[b]thiophene to 2-ethylthiophenol and ethylbenzene.

  配体框架上的对苯乙烯基取代基使三重三膦分子-C(CH2PPh2)3 能够通过自由基共聚作用作为悬垂基团被引入聚苯乙烯基质中；与铑（I）结合后，聚三磷酸盐材料成为一种有效的异相催化剂，可将苯并[b]噻吩氢解为 2-乙基噻吩酚和乙苯。
