• Friedel-Crafts acylation of 2-trimethylsilylnorbornene. Effect of acyl group on the position of attack
  作者：Gopalpur Nagendrappa、Noor Shahina Begum

  日期：1999.6

  The acylation of 2-trimethylsilylnorbornene 1 in the presence of aluminium chloride gives minor quantities of the expected 2-norbornenyl ketones 4. The formation of 3 and 5 as major products indicates that either α-or β-attack takes place predominantly depending on the nature of the acyl group, and the β-silicon effect is not a decisive factor. The β-silyl cation intermediate 2 mainly leads to nortricyclyl
