  Alkyl-substituted indenyl titanium precursors for syndiospecific ziegler-natta polymerization of styrene

  摘要：

  A variety of 1- and 3-substituted alkylindenes (R = H, Me, Et, tert-butyl, Me(3)Si) as well as 2-methylindene and 3-(methylthio)indene have been prepared in good yields. The substituted indenes were converted into trimethylsilyl derivatives via reactions of intermediate organolithium complexes with chlorotrimethylsilane. The corresponding titanium complexes, (R-Ind)TiCl3, were synthesized in excellent yield from reactions of the trimethylsilyl derivatives with TiCl4. The titanium complexes were evaluated as styrene polymerization catalysts in toluene solution when activated by methylaluminoxane. Activities increased in the order: Cp < H(4)Ind < Ind < 1-(Me)Ind < 2-(Me)Ind. A steep drop in activity was observed when R = Et, tert-butyl, and Me(3)Si, corresponding to an increase in the steric bulk of the substituent in the catalyst precursor. 1-(MeS)IndTiCl(3) was found to be ineffective as a styrene polymerization catalyst. Syndiospecificities of the titanium complexes were generally very good (65-98%).

  case of the silylindene. The isomerization of the hydralumination adduct could occur either by carbonaluminum bond inversion or by dehydralumination. The former process took place readily in the absence of Lewis bases, but the latter process required elevated temperatures and protracted times. The stable cis-hydralumination adducts could be protodealuminated with retention of configuration at the CAl

  为了确定立体化学，区域化学以及结构对反应性的影响，用二异丁基铝氢化物对一系列环状烯烃进行水合铝化反应。观察到的反应性等级为：> 1，1-二甲基-3-三甲基甲硅烷基茚> 1-甲基ena> 1，1-二甲基茚> 1-苯基ac→1，1-二甲基-3-苯基茚。通过在供体溶剂中工作，证明了顺式-水合铝化是动力学控制的添加方式。3-取代-1,1-二甲基茚的反应性反映了极性效应，而1-取代的反应性则反应了空间效应。除硅烷基茚的情况外，水合铝化的区域化学通常由空间因素决定。水合铝酸盐加合物的异构化可能通过碳铝键反转或脱水铝化而发生。前一种方法很容易在没有路易斯碱的情况下进行，但是后一种方法需要高温和延长时间。稳定的顺式尽管烯基体系产生了大量的1,3-二氢ac烯，但β-水合铝化加合物仍可被原脱铝，并保留CAl键的构型。通过氘标记，1 H NMR和化学降解研究阐明了这些异常水解产物的性质。为了允许进行上述研究，明确地合成了完整的C

  A ruthenium-catalyzed C–H alkylation/cyclization sequence is presented to prepare silyl indenes with atom and step-economy. This domino reaction is triggered by acyl silane-directed C–H activation, and an aldehyde controlled the following enol cyclization/condensation other than β-H elimination. The protocol tolerates a broad substitution pattern, and the further synthetic elaboration of silyl indenes

  Reactions of benzoylsilane with benzylpentacarbonylmanganese (1) give ortho-eta(2)-manganese complexes in high yield. The derived aldehyde complex can then be formed by fluoride-catalysed desilylation of the acylsilane complex. Coupling reactions of the acylsilane complexes with alkenes or alkynes are reported.
