  stoichiometric or a little excess amount of NaBH4 was treated with [MX2(PR3)2] (M=Co, Ni, X= halides, SCN, PR3=PPhnEt3−n) in THF–1,2-dimethoxyethane to form monohydride species which were active for isomerization of 1-butene. The reaction was accelerated by excess PPh3 in [CoX2(PPh3)2]–NaBH4 systems. Other catalytic systems have optimum ratios of excess phosphine to metal for getting maximum activities. Thiocyanate–metal

  cobalt(II) phosphine complexes have been synthesized by reacting cobalt(II) chloride with various mono- and diphenylalkylphosphines (PRxPh3 − x; R = methyl, ethyl, allyl, propyl, isopropyl, cyclohexyl; x = 1, 2). For some of these complexes single crystals were obtained and their molecular structure, were determined by X-ray diffraction method. All the complexes were then used in association with MAO for

• Solvent effect on cis-1,4-specific polymerization of 1,3-butadiene with CoCl2(PRPh2)2–EASC catalytic systems

  A series of phosphine-containing cobalt complexes [CoCl2(PRPh2)2, R = Ph (1), Cy (2), nPr (3), Et (4), Me (5), H (6)] has been used for the highly active and stereospecific polymerization of 1,3-butadiene upon activation with ethylaluminum sesquichloride (EASC). The high catalytic activities and polybutadienes with high cis-1,4 selectivity were obtained in the solution polymerization in toluene. The conversion of butadiene and the microstructure and molecular weight of the resulting polymers were affected by reaction parameters and the R group on the phosphine ligand. The dispersion medium was also a sensitive factor for the current catalytic systems, influencing the catalytic activity and properties of products. In comparison with the solution polymerization in toluene, the heterogeneous polymerization in isooctane yielded slightly lower catalytic activity, cis-1,4 content and molecular weight under similar reaction conditions.

  一系列含膦钴配合物[CoCl2(PRPh2)2, R = Ph (1), Cy (2), nPr (3), Et (4), Me (5), H (6)]在三异丁基铝（EASC）活化下，对1,3-丁二烯进行了高活性且具有立体选择性的聚合反应。在甲苯溶液聚合中获得了高催化活性和高顺-1,4选择性的聚丁二烯。丁二烯的转化率以及所得聚合物的微观结构和分子量受到反应参数和膦配体上R基团的影响。分散介质也是当前催化体系中的敏感因素，影响催化活性和产物性质。与甲苯溶液聚合相比，在异辛烷中的非均相聚合在相似反应条件下产生了稍低的催化活性、顺-1,4含量和分子量。
