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〓.

Sweet is the breath of morn, her rising sweet, With charm of earliest Birds; pleasant the Sun When first on this delightful Land he spreads His orient Beams, on herb, tree, fruit, and flour, Glistring with dew; fragrant the fertil earth [ 645 ] After soft showers; and sweet the coming on Of grateful Eevning milde, then silent Night With this her solemn Bird and this fair Moon, And these the Gemms of Heav'n, her starrie train: But neither breath of Morn when she ascends [ 650 ] With charm of earliest Birds, nor rising Sun On this delightful land, nor herb, fruit, floure, Glistring with dew, nor fragrance after showers, Nor grateful Eevning mild, nor silent Night With this her solemn Bird, nor walk by Moon, [ 655 ] Or glittering Starr-light without thee is sweet.

同你谈话，我总是忘掉了时间，以及季节的转换，任何时刻都感到高兴：早晨呼吸清鲜空气，和早鸟一同歌唱，觉得舒畅；初升的太阳，在愉快的大地上，抛撒他那蔷薇色的光线，照耀着草、木、花、果，带露晶莹；细雨阵阵过后，丰腴的土地流芳；夕暮来临时心旷神怡，接踵而至的是沉静的夜，她有严肃的鸟儿、美丽的月亮和繁星，天上的宝石。但没有你时，一切都觉变了样：晨风不鲜，早鸟的歌唱不欢，尽管有太阳照耀大地，有草木花果的露珠晶莹，有雨后的流芳，愉悦的夕暮来临，沉静的夜也带来她那严肃的鸟儿，在月亮或亮晶晶的星光下散步，这一切，若没有你便没有快乐。
