  Synthesis and Characterization of Bulky Cationic Arylalkylaluminum Compounds

  摘要：

  The cationic m-terphenyl-substituted organoaluminum compounds [Dipp*AlEt][CH(6)B(11)Cl(6)] (3; Dipp* = 2,6- (2,6-Cl(2)C(6)H(3))(2)C(6)H(3)-), [DCpAlEt][CH(6)B(11)Cl(6)] (4; Dcp = 2,6-(2,6-Cl(2)C(6)H(3))(2)C(6)H(3)), [Dipp*AlEt] [CH(6)B(11)I(6)] (5), and [DcpAlEt][CH(6)B(11)I(6)] (6) have been obtained by ethide elimination through trityl or preferably silylium salts from the precursors Dipp*AlEt(2) (1) and DcpAlEt(2) (2). The crystal structures of compounds 3-5 reveal the presence of cation anion adducts involving two halides of the carborane anions, and the NMR spectroscopic data and solubility properties indicate such an interaction for 6. The interactions of the hexaiodocarborane anion with the [Dipp*AlEt](+) cation are stronger than those of the hexachlorocarborane anion. Interestingly, cation center dot center dot center dot anion contacts are preferred to intramolecular Al center dot center dot center dot Cl interactions in the Dcp species 4. Compound 4 forms the bisamine adduct [DcpAlEt(NH(2)t-Bu)(2)] [CH(6)B(11)I(6)] (8) upon exposure to tBuNH(2), and compounds 3 and 4 slowly catalyze the alkylation of benzene with 1-hexene. The compounds have been characterized by (1)H, (13)C, and (11)B NMR spectroscopy and by X-ray crystallogrzphy in the case of 1-5, 7, and 8.

  with alkynes and alkenes are described. It is shown that hydroalumination of the terminal alkynes HCCSiMe3 and HCCPh readily occurs under mild conditions via the cis-addition of the Al–H moiety across the CC triple bond with no evidence of hydrogen elimination. Hydroalumination was observed also with a range of terminal olefins, but no reactivity was observed with internal alkenes or alkynes. The relatively

  在空间上拥挤的伯烷（Ar Pr i 8 AlH 2）2（Ar Pr i 8 = C 6 H-2,6（C 6 H 2 -2,4,6-Pr i 3）2 -3的反应，描述了具有炔烃和烯烃的5-Pr i 2）。结果表明，末端炔烃HCCSiMe 3和HCCPh的氢化铝在温和条件下容易通过顺式发生-在CC三键上加成Al-H部分，没有消除氢的迹象。在一系列末端烯烃中也观察到了氢铝化反应，但是与内部烯烃或炔烃未观察到反应性。（Ar Pr i 8 AlH 2）2的较高反应性归因于大三联苯取代基的空间拥挤，这有利于铝烷的离解并增加了单体中更具反应性的三配位铝位点的可用性。按照这种观点，研究了三种主要丙氨酸（Ar Pr i 8 AlH 2）2（Ar Pr i 4AlH 2）2（Ar Pr i 4 = C 6 H 3 -2,6（C 6 H 3 -2,6-Pr i 2）2）和（Ar Me 6 AlH 2）2（Ar Me
