• Palladium(0) Complex-Catalyzed Debrominative Coupling of (Tribromomethyl)- and (Dibromomethyl)benzenes to Diarylacetylenes and 1,2-Diarylethenes
  作者：Shuntaro Mataka、Guo-Bin Liu、Masashi Tashiro

  DOI：10.1055/s-1995-3878

  日期：1995.2

  Palladium(0)-triphenylphosphine complex-catalyzed debrominative coupling reaction of (tribromomethyl)benzenes gave diarylacetylenes or a mixture of (E)- and (Z)-α,β-dibromostilbenes depending upon the substrate and the solvent being used. On the other hand, (dibromomethyl)benzenes afforded (E)-stilbenes selectively under the same reaction conditions.

• Photothermal Side-Chain Bromination of Methyl-, Dimethyl-, and Trimethylbenzenes with<i>N</i>-Bromosuccinimide
  作者：Shuntaro Mataka、Guo-Bin Liu、Tsuyoshi Sawada、Masayoshi Kurisu、Masashi Tashiro

  DOI：10.1246/bcsj.67.1113

  日期：1994.4

  Tri- and dibromination of methyl-, dimethyl-, and trimethylbenzenes with N-bromosuccinimide were accomplished by photothermal reaction with a tungsten lamp in carbon tetrachloride or benzene. (Dibromomethyl)arenes and (tribromomethyl) derivatives were produced depending upon a solvent used and a substituent on the benzene ring. In the bromination of methylbenzenes without a substituent on the ortho-position, (tribromomethyl)benzenes were formed. On the other hand, ortho-substituted methylbenzenes gave (dibromomethyl)benzenes. α,β-Dibromo-1,2-diarylstilbenes were formed via the debrominative carbon–carbon coupling reaction of (tribromomethyl) benzenes upon irradiation with a tungsten lamp.

  采用钨丝灯在四氯化碳或苯溶剂中进行光热反应，实现了N-溴代琥珀酰亚胺对甲基苯、二甲基苯和三甲基苯的二溴化和三溴化。根据所用溶剂和苯环上取代基的不同，生成了二溴甲基芳烃和三溴甲基衍生物。在邻位无取代基的甲基苯的溴化反应中，生成了三溴甲基苯。另一方面，邻位取代的甲基苯生成了二溴甲基苯。通过三溴甲基苯在钨丝灯照射下的脱溴碳-碳偶联反应，生成了α,β-二溴-1,2-二芳基苯乙烯。
