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〓.

By the bio-assay directed fractionation of the volative constituents.dimethyl disulfide,allyl methyl trisulfide,allyl methyl sulfide and diallyl disulfide were found to increase the beating rate and beating amplitude in a standard medium,but the compund 2-pentanone without sulfide did not affect either of them.

从具有生物活性的挥发性提取物中分离得到的二甲基二硫、烯丙基甲基三硫、烯丙基甲基硫醚和二烯丙基二硫对培养心肌细胞心率和振幅均有不同程度的增强作用，而不含硫的2-戊酮则没有作用。

The surface-enhanced Raman scattering spectroscopy analysis verifies that two nitrogen-containing or sulphur-containing aromatic heterocyclic compound s were chemisorbed onto the Ag-plated carbon fibers and formed a lie-down phase.

In this experimental study firstly a sulphur-bearing alkanethiol-derivatised gold nanoparticles has been selected and prepared. The alkanethiol-derivatised gold was put in the mud-stone samples bearing terreau. In varies elevated temperature the gas products were collected by foam plastics in a special installation. The measurements on the contents of gold in foam plastics and on the composition of gas phase were carried out and the comparisons for various samples were made.
