In this thesis, two series compounds of thiadiazole (2a~2f) and benzothiazole (5a~5f) were synthesized by using the reagent of iodobenzene diacetate. We also bound the iodobenzene diacetate reagent to the resin and applied it to synthesize thiadiazole and benzothiazole compounds.

在ZSM-5分子筛催化剂上，从芳烃迁移反应向芳烃生成反应的过渡大约发生在转化率55%附近，芳烃迁移和芳烃生成反应对苯生成的贡献分别约为20%和80%，原料中约10%的烷基苯会发生脱烷基反应生成苯。

With the Y zeolite the turning point from aromatics shift to aromatics generation happened at the conversion of about 30%.The respective contributions to benzene formation from aromatics shift and aromatics generation were about 36% and 64%, and the dealkylation of about 5% of alkylbenzene present in the feed was also helpful to form benzene.

Data analysis shows that the total amount of PAHs in the sediments of north Taihu Lake is obviously higher than that at the central and south Taihu Lake, and that there is a little difference between the contents of PAHs of high molecular weight and low molecular weight, while the ratio of PAHs varies in different sections of the lake. Through the statistical analysis of the ratio of fluoranthene to pyrene, it is concluded that PAHs mainly come from oil burning with part of them from coal and wood burning.

分析结果表明，太湖北部的多环芳烃总量明显高于中部和南部，低分子量多环芳烃与高分子量多环芳烃的含量差别不大，但在地域上比例有所变化；根据荧蒽/芘的比值统计，多环芳烃主要来源于石油燃烧，部分为煤和木材的燃烧形成。

Base played a crucial role in this reaction: in the Pd2/L1 catalyzed α-arylation of ethyl malonate, K3PO4 is the base of choice; in the α-arylation of ethyl acetoacetate, K2CO3 is the most effective base.

在这类催化反应中，碱的选择具有重要的影响：以K3PO4为碱， Pd2/L1催化体系在丙二酸二乙酯的α-芳基化中，富电子溴代芳烃显示较好的活性； Pd2/L1催化的乙酰乙酸乙酯α-芳基化时，以 K2CO3为碱，催化体系显示较好的活性，这个催化体系可控制反应得到α-芳基乙酰乙酸乙酯，而不是脱乙酰基的产物。
