Second, using DBU as the base for enolization of propargylic esters of unsaturated acids 18e-k, we developed a tandem Ireland-Claisen rearrangement /isomerization reactions. It has been shown that the reaction sequence affords triene molecules 42a-b and 43a-b in moderated to high yields. Interestingly, with allyl hexa-3,5-dienoates 18i-j as the substrate, the rearranged products underwent further aromatization to give uniquely substituted benzyl acids 44a-b.
其次，以含有活泼质子的烯酸炔丙酯18e-k为底物，在DBU为烯醇化碱、TMSCl为硅试剂的条件下，底物18e-h发生了Ireland-Claisen重排/异构化串联反应，得到完全共轭的三烯类化合物42a-b及43a-b；而以己二烯酸炔丙基酯18i-j为底物时，重排/异构化后的产物进一步发生电环化等反应最终得到芳构化产物——取代苯甲酸类化合物44a-b。

To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.
为了开发新的合成方法，研究了苯并咪唑盐与各种亲核试剂（活泼芳环与杂原子亲核试剂）的反应，发现苯并咪唑盐不与活泼芳环及杂原子亲核试剂发生2位加成反应；在与体积较大的位阻型N亲核试剂邻苯二甲酚亚胺反应时，未得到亲核试剂与极化的C＝N的加成产物，而是得到N烷基化的邻苯二甲酰亚胺，进一步研究表明，苯并咪唑盐将1（3）位N上的烷基转移给了邻苯二甲酰亚胺，并讨论了其反应机理和取代基，溶剂效应。

The studies found that compatibility between ZDDP and succinimide dispersants primarily depended upon active α-amino-group content in succinimides. The active α-amino-group content was affected by the alkylation and amination processes, and also affected by the structure of polyisobutylene in succinimides.
研究结果表明，丁二酰亚胺与 ZDDP 的相互作用主要取决于丁二酰亚胺中活泼的伯胺氮含量，而伯胺氮含量则决定于丁二酰亚胺在生产中的烃化、胺化工艺和聚异丁烯基的结构。

In our research, through derivatization of stable calix[4]pyrroles, active substituting units were jointed on the calixpyrrolic skelecton. After acylamide and free radical transfer reaction, the preparation of new calix[4]pyrrole-bonded stationary phases were fulfilled. the separation abilities of them to inorganic and organic anions and medicines were exploited and new analytical methods were established. The separation mechanisms were discussed. At the same time, through using calix[4]pyrroles as additives in CZE to influence the electrophoresis of inorganic anions, the recognition mechanisms and influencing factors in supramolecular chemistry were also studied.

alkyne：炔烃
C=C大于C―C单键,但又小于C―C键能的2倍,由此推断,π键的键能小于σ键的键能.π键不如σ键牢固,比较容易断裂,易发生化学反应,从而表现出π键比σ键活泼,烯烃比烷烃易发生加成反应.炔烃(alkyne)的结构特征是C≡C中的碳原子均为sp杂化,
