  N-溴代琥珀酰亚胺在取代烷基芳烃的超声和微波辅助溴化反应中的化学选择性不同

  摘要：

  各种烷基芳基与N-溴丁二酰亚胺在纯净或水中的超声和微波辅助溴化反应显示出不同的化学选择性。因此，在超声波作用下，水中发生环取代，而在微波作用下，侧链α-溴化和环取代都发生。对于纯净的反应物，微波辅助反应中侧链α-溴化反应占主导地位。在水的存在下，微波促进的溴化的化学选择性类似于使用传统方法观察到的化学选择性。

  日期：1993.3

  The ring-substituted 1-naphthylmethyl esters of phenylacetic (3a-k) and 3-phenylpropanoic (5a-c) acid have been photolyzed in methanol solvent. The major products of these reactions are derived from two critical intermediates, the 1-naphthylmethyl radical/acyloxy radical pair and the 1-naphthylmethyl cation/carboxylate anion ion pair. The radical pair results in formation of the in-cage coupled products
