The chapter two was focused on the samarium diiodide promoted organic reactions and their applications in organic synthesis, firstly, a new synthesis of highly substituted cyclopentadienes from a,β-alkynone promoted by samarium diiodide was investigated and the highly substituted cyclopentadienes were prepared in moderate to good yields under mild conditions. Secondly, the Michael addition and Michael-aldol tandem reaction of diorganyl diselenides or diorganyl disulfides with α,β-alkynones mediated by samarium diiodide were studied and a series of alkenylsulfides and alkenylselenides were prepared in good yields. Then the highly regioselecfive nucleophilic addition of the allylsamarium bromide to α,β-alkynones were explored. We found that the allylsamarium bromide reacts with α,β-alkynones to afford regiospecificly 1. 2-nucleophilic addition products in good yields under mild condition. At last we studied the coupling reaction of aryl halides promoted by NiCl〓/PPh〓/Sm〓.

第二章 研究了二碘化钐、金属钐促进的有机反应：1、二碘化钐促进下α，β-炔基酮的偶联环化反应，提供了一种制备多取代环戊二烯的新方法；2、二碘化钐促进下的二硫醚、二硒醚与α，β-炔基酮的Michael加成反应，为高产率地制备多取代的烯基硫或烯基硒化合物提供了方便可靠的新方法；3、二碘化钐促进下的二硫醚、二硒醚与α，β-炔基酮和醛、酮的Michael—aldol串联反应，提供了一种一锅法高产率地制备多取代的含硫的烯丙基醇或含硒的烯丙基醇类化合物的方便可靠的原子经济性的新方法；4、烯丙基溴化钐与α，β-炔基酮的高度区域选择性的1，2-亲核加成反应；5、NiCl〓/PPh〓/Sm〓促进的卤代芳烃的偶联反应-一种从各种卤代芳烃制备联苯类化合物的有效方法。

Blessed with one of the most exciting new voices in years, Whitney Houston sings the hell out of the pleasant but undistinguished pop-soul tunes on her album, which was put together by a consortium of top producers: Michael Masser, Jermaine Jackson, Kashif, Narada Michael Walden.

被誉为近年来最令人激动的新嗓音之一，惠特尼·休斯顿在她的专辑里唱出了令人愉快但毫无特色的流行-灵魂风格的音乐地狱。这张专辑是由一个顶尖制作人团队拼合在一起的：Michael Masser，Jermaine Jackson，Kashif，Narada Michael Walden。

1 Heptane, it was revealed that the Cr〓/ Catsan and ZnCl〓 could catalyze the Michael addition of pyrrole with conjugate olefine at α-position of pyrrole to get mono- or bi-Michael addition product selectively under mild condition in good yield. Totally, forty-six new compounds, including thirty target compounds, were prepared.

在探索7-氮杂桥环母体的构建方法过程中，发现了Cr〓／Clay和ZnCl〓可有效地催化吡咯的α-位与多种共轭烯烃发生Michael加成反应，可在温和的条件下，以良好的收率选择性地得到单或双Michael加成产物。
