  P-heterocyclic γ-ketophosphonates were synthesized by the Michael reaction of methyl vinyl ketone with dibenzo-1,2-oxaphosphorine 2-oxide, 1,3,2-dioxaphosphorine 2-oxide and benzo-1,3,2-dioxaphospholane 2-oxide, respectively. In the first two cases, 50% of 1,8-diazabicyclo[5.4.0[undec-7-ene had to be used that was also required in the addition of dibenzooxaphosphorine oxide to cyclohexenone to result

  P-杂环γ-酮膦酸酯是通过甲基乙烯基酮与二苯并-1,2-氧杂膦2-氧化物、1,3,2-二氧杂膦2-氧化物和苯并-1,3,2-二氧杂膦2-氧化物的迈克尔反应合成的氧化物，分别。在前两种情况下，必须使用 50% 的 1,8-二氮杂双环[5.4.0[undec-7-ene]，这也是将氧化二苯并氧杂膦添加到环己烯酮中以形成相应的 γ-酮膦酸盐。在用等摩尔量的三甲基铝活化后，将二苯并氧杂膦氧化物加成到反应性较低的 1,2-二氢膦氧化物中，得到 3-P(O)<-1,2,3,6-四氢膦氧化物，将其加入催化加氢得到相应的 1,2,3,4,5,6-六氢氧化膦。© 2008 Wiley Periodicals, Inc. 杂原子化学 19：288-292, 2008; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20421

  The invention relates to novel organo phosphorus P-chiral optically active compounds of formula (I) having a hydroxyl, mercapto, amino, carboxyl, sulfonyl group on aryl near a phosphorus atom, to the preparation and the use thereof in then asymmetrical catalysis of unsaturated compounds. Novel acylphosphine optically pure ligands embodied in the form of transition metal complexes exhibit an increased activity and enantloselectivity, in particular in asymmetrical hydrogenation, in comparison with the same type Uganda such as DiPAMP.

  The instant invention teaches a method for forming a syndiotactic 1,2-polybutadiene product having a higher syndiotacticity and a higher melting temperature than syndiotactic 1,2-polybutadiene produced using chromium catalysts known in the prior art. The method includes polymerizing 1,3-butadiene in solution with a solvent, in the presence of catalytically effective amounts of (a) an organomagnesium compound; (b) a chromium compound; and, (c) a cyclic hydrogen phosphite.

• Process for producing syndiotactic 1,2-polybutadiene and iron-based catalyst composition for use therein

  A catalyst composition comprising (a) an iron-containing compound, (b) a cyclic hydrogen phosphite, and (c) an organoaluminum compound is disclosed for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. The use of the catalyst composition of this disclosure avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 125 to about 175 °C by variations in the catalyst components and the component ratios. The ability to vary the melting temperature over such a broad range with a single catalyst composition is very desirable. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions wherein it can crosslink with conventional rubbers using conventional crosslinking agents.

  本发明公开了一种由(a)含铁化合物、(b)环状亚磷酸氢盐和(c)有机铝化合物组成的催化剂组合物，用于将 1,3-丁二烯聚合成对位 1,2-聚丁二烯。使用本公开的催化剂组合物可以避免使用二硫化碳和卤代溶剂等有害环境的成分。通过改变催化剂组分和组分比例，辛二聚丁二烯的熔化温度可在约 125 ℃ 至约 175 ℃ 之间变化。使用单一催化剂成分就能在如此大的范围内改变熔化温度，这是非常理想的。辛二聚丁二烯可用作塑料或橡胶组合物的添加剂，其中辛二聚丁二烯可使用常规交联剂与常规橡胶交联。
