Three kinds of novel N-heterocyclic carbene allyl palladium complexes (Catalyst 1, 2 and 3) were synthesized. Norbornene polymerizations were carried out using three catalysts activated with methylaluminoxane in toluene.

研究了以3种N-杂环卡宾螯合烯丙基钯配合物1、2和3为催化剂，甲苯为溶剂，甲基铝氧烷为助催化剂催化降冰片烯的聚合。

The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.

研究表明高精度的密度泛函理论计算能够用来预测纳米管的13C化学位移，理论研究的结果揭示了氮烯、卡宾以及1，2和1，4氟化的单壁纳米管的若干13C信号特征化学位移值，为实验NMR谱图的归属提供了一定的依据，并且可通过与实验相结合来监测表面官能化碳纳米管加成反应是否发生以及确认其加成方式。

The mechanism of cycloaddition reaction between singlet carbene and Formylchloride has been investigated by using ab initio MO theory of the restricted Hartree-Fock at HF/3-21G~* level.

用限制的H artree-Fock从头算分子轨道理论研究了单重态卡宾与甲酰氯环加成反应的机理。

Teacher: It's a carbine knife.

A frick FLEC commander said the togolese Togolese team was not target targeted in the attack . But but was a casulty casualty of the war.

卡宾达海外领地解放阵线的一位指挥官说，此次突袭的目标并非多哥足球队，他们只是战争的牺牲品。

In the early 1950s a new interstate highway was planned to bypass the town of Corbin.

50年代初一条新计划的州际公路要横穿卡宾小镇。

His main opponent, Robert Corbin, took over his party only three years ago, but like many of his colleagues has been in politics since the 1960s.

他的主要政敌，罗伯特？卡宾三年前接管了他所在的政党，但是就像1960年代以来他的许多政治同行一样。

Corbin pondered his next movie as he carefully climbed the large rock.

当卡宾小心谨慎攀岩着巨大的岩石的时候他在深思着他的下一部电影。

The thermolysis of the isomerized products derived from norbornadiene-coordinated carbonyl iron complexes gave two sorts of the thermolytic products based on different substituents on the olefin ligands. One is the corresponding diiron dimer complex, and the other is the complex in which the C-C bond of the cycloolefin ligand is broken.

以降冰片二烯三羰基铁络合物衍生出来铁卡宾络合物的异构化产物的热解，随着烯烃配体上取代基的不同，而分别得到了络合物发生二聚和烯烃配体发生碳碳键断裂的两类热解产物。

General approaches involve the nucleophilic cycloalkylation, carbenoids addition of certain amino acid derivatives and derivatization from simple cyclopropane compounds.

制备方法包括对简单氨基酸衍生物的亲核环烷基化、卡宾加成以及简单环丙烷化合物的衍生化合成等。
