The dissertation mainly consists of two parts:1. The Reaction Chemistry of Alkynes under Palladium Catalysis Part 1 studies the reaction α,β-unsaturated carbonyl compounds with alkenylpalladium intermediate generated by nucleopalladation, and discovered 1 the Pd-catalyzed tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls,2 the four-component tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls, 3 the tandem intramolecular oxypalladation-conjugate additionreaction of alkynoic acids with α,β-enals. These new reactions provide notonly efficient highly stereoselective methods for the synthesis of γ,δ-unsaturated,polyunsaturated carbonyl compounds and γ-lactonic aldehydes, but also thebasic transformations for a number of C-C bond formation reactions which can be usedto design synthesis of many acyclic, cyclic or polycyclic compounds.
本论文的主要工作分为两个部分:一、钯催化下炔烃的反应化学在本小组前人工作的基础上,我们详细研究了炔烃亲核钯化产生的烯基钯中间体与α,β-不饱和羰基化合物的反应,发现两价钯催化下卤离子-炔烃-α,β-不饱和醛酮的串联加成反应、卤离子-炔烃-α,β-不饱和醛酮的西组分串联加成及炔酸分子内氧钯化-串联Michael型加成反应;由此发展了γ,δ-不饱和醛酮、多不饱和羰基化合物和带有醛酮基侧链的γ-丁内酯衍生物的高立体选择性合成方法,这一过量卤离子存在下的烯基钯对α,β-不饱和羰基化合物共轭加成反应的发现,为大量碳-碳键形成反应的实现提供了基础,使我们能够从这一基本反应出发,设计和开发多种分子内、分子间的碳碳成键反应,以好的立体、区域选择性组建开链、环状及多环类型的化合物。

Based on the previous research on the deposition of amorphous/microcrystalline silicon tandem solar cells, silane concentration for the deposition of microcrystalline bottom cell was selected to further optimize the performance for micromorph tandem solar cells using very high frequency technique. Finally, micromorph silicon tandem solar cell with 11.02%(Area=1.0cm2) initial conversion efficiency has been fabricated at a certain silane concentration and suitable light trapping structure.
采用甚高频等离子体增强化学气相沉积技术,在前期我们单室沉积的微晶硅薄膜太阳电池和非晶硅/微晶硅叠层太阳电池研究的基础上,通过对微晶硅底电池本征层硅烷浓度的优化,获得了初始效率达到11.02%(电池面积1.0cm2)的非晶硅/微晶硅叠层太阳电池。
