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〓.

The normally brominated Baylis-Hillman adducts were formed as the major product at low temperature. While at room temperature or heating, the α,γand β,β-dibrominated compounds were formed as the major products using 3-butyn-2-one and methyl propiolate or propynenitrile as substrate, respectively.

贫电子炔类化合物的Baylis-Hillman反应的研究在这部分工作中我们发现在用TiBr〓或BBr〓为Lewis酸催化贫电子炔类化合物和芳香醛的Baylis-Hillman反应时，温度对反应的影响很大：当反应在低温下进行时，通常生成的是正常的β-溴代的Baylis-Hillman反应产物；而在室温或加热条件下反应，以丁炔酮为底物时，主要生成的是α，γ-二溴化合物，而以丙炔酸甲酯及丙炔腈为底物时，主要生成的是β，β-二溴化合物。
