Phenyl or polyphenyl substituted epoxides serve as excellent precursors to phenyl or diphenyl carbenes. 某些苯代或多苯环氧化物是制取带苯环或二苯碳烯的极好原料。
Research on the carbenes 关于卡宾的研究
Properties and syntheses of N-heterocyclic carbenes and their metal complexes N-杂环卡宾及其金属络合物的性质和合成方法
In the paper the properties and syntheses of N-heterocyclic carbenes and their metal complexes are reviewed. 本文对N杂环卡宾及其金属络合物的性质和合成方法进行了综述。参考文献30篇。
The mechanism and the various factors influencing the 1,4 addition of Carbenes to dienes as well as the applications of these reactions in organic synthesis are reviewed. 讨论了卡宾1,4-加成反应的机理、影响因素以及1,4-加成在有机合成中的特殊应用。
In early years, most of carbenes is N-heterocyclic carbene, the reactions about it were limited metal complexes. 早期的卡宾多是N-杂环卡宾的金属络合物,但是他们参与的反应比较局限,仅限于金属络合物的研究。
Carbenes play an important role in organic chemistry, since it be determined intermediate. 卡宾自被确认为是一种反应中间体后,就在有机化学中扮演着重要的角色。
N-heterocyclic carbenes ( NHCs) are a class of a-donor with strong electron-donating ability. And their transition metal complexes have a wide range of applications in catalysis, medicine and materials. N-杂环卡宾(NHCs)是一类具有很强给电子能力的σ-配体,其过渡金属化合物在催化、医药和材料方面有着广泛的应用。
It is ascertained the whole tandem reaction sequence pivots on the nucleophilicity of thiazole carbenes, and the solubility of thiazolium precursors has an enormous effect on the reactions. 整个反应的历程取决于噻唑卡宾的亲核性,而卡宾前体在有机溶剂中的溶解性对反应也有较大的影响。
