Pd/Cu catalyzed homo-coupling reactions of 2-iodo-3-iodomethyl-1,4-diarylnaphthalene in the presence of arylacetylene
摘要:
Palladium/CuI catalyzed reactions of 2-iodo-3-iodomethyl-1,4-diarylnaphthalenes in the presence of arylacetylenes produced the corresponding sp(3)-SP3 homo-coupling products 1,2-bis(3-iodonaphthalen-2-yl)ethane in moderate to good yields. (c) 2007 Elsevier Ltd. All rights reserved.

Reactions of arylvinylidenecyclopropanes 1 with equimolar amount of bromine or iodine at low temperature produced the corresponding addition products 2,3 and 5, 6 in moderate to good yields at -40 °C and -100 °C, respectively. On the other hand, the reactions of 1 with equimolar amount of iodine gave the corresponding iodinated naphthalene derivatives 4 via the corresponding addition products 3 under
芳基亚乙烯基环丙烷 1 与等摩尔量的溴或碘在低温下反应,分别在 -40 °C 和 -100 °C 下以中等至良好的产率生成相应的加成产物 2,3 和 5、6。另一方面,1与等摩尔量的碘在25°C的类似条件下通过相应的加成产物3反应得到相应的碘化萘衍生物4。已经介绍了加成产物 6a 的进一步转化。
