  Treatment of [PdCl₂(cod)] with tetrabenzyltin gives the benzylpalladium complex [PdCl(CH₂Ph)(cod)] (cod = 1,5-cyclooctadiene), 1a, whose structure has been determined by X-ray crystallography. It adopts approximate square-planar geometry, with the double bonds perpendicular to the square plane. The corresponding ethylpalladium derivative 1b has been prepared by a similar method, but it is considerably less stable. It decomposes by (β-elimination to produce ethene and a transient hydride complex, which either undergoes migratory insertion to give [Pd₂(μ-Cl)₂(η¹,η²-C₈H₁₃)₂], 2a, or dinuclear reductive elimination with a second molecule of 1b to produce ethane, [PdCl₂(cod)], free cyclooctadiene, and palladium metal. Complex 2a has also been prepared by reaction of [PdCl₂(cod)] with NaBH₄. At higher temperatures 2a converts to an equilibrium mixture with its η³-allyl isomer, 2b. Reactions of [PdCl₂(cod)] or K₂PdCl₄ in the presence of cyclooctadiene in aqueous solution to produce 2a or 2b have also been investigated. Key words: palladium, diene complexes, allyl complexes, isomerization, β-elimination.

  [PdCl2(cod)]与四苄基锡反应得到苄基钯配合物[PdCl(CH2Ph)(cod)]（cod = 1,5-环辛二烯），1a，其结构已通过X射线晶体学确定。它采用近似平面正方形几何结构，双键垂直于正方形平面。相应的乙基钯衍生物1b已通过类似方法制备，但其稳定性较低。它通过（β-消除）分解产生乙烯和一种瞬态氢化物配合物，后者要么经历迁移插入形成[Pd2(μ-Cl)2(η1,η2-C8H13)2]，2a，要么与第二分子的1b进行双核还原消除产生乙烷，[PdCl2(cod)]，游离的环辛二烯和钯金属。配合物2a也可通过[PdCl2(cod)]与NaBH4反应制备。在较高温度下，2a转化为与其η3-烯丙基异构体2b的平衡混合物。已研究了[PdCl2(cod)]或K2PdCl4在水溶液中与环辛二烯反应产生2a或2b的反应。关键词：钯，二烯配合物，烯丙基配合物，异构化，β-消除。

  decomposition of [Pd2(CH2Ph)2(μ-Cl)(μ-dppm)2]Cl was found to be first order in A-frame and resulted in quantitative formation of [Pd2Cl2(μ-dppm)2] and 1,2-diphenylethane. The methyl and aryl complexes underwent both reductive elimination and hydrogen abstraction reactions.

  The addition of a variety of organolithium reagents to 1-napththyloxazolines and 2-naphthyloxazolines followed by trapping with electrophiles leads to high yields of the title compounds. Very high stereoselectivity characterizes the present process in that the electrophile enters from the naphthalene face opposite to the entry of the organolithium reagent. A number of organolithiums have been investigated

  将多种有机锂试剂添加到1-萘恶唑啉和2-萘恶唑啉中，然后用亲电试剂捕集，可得到高产率的标题化合物。很高的立体选择性是本发明方法的特征，因为亲电试剂从与有机锂试剂进入相反的萘面进入。已经研究了许多有机锂，并且发现从四取代的锡烷原位生成有机锂提供了用于将亲核加成到萘中的优良试剂。恶唑啉的去除有效地导致了甲酰基或羟甲基-1,2-二氢萘。
