5- R -3-(2-吡啶基)-1,2,4-三嗪与芳烃相互作用的研究:逆需求aza-Diels–Alder反应与芳烃介导的多米诺过程†
摘要:
已经研究了取代的5 - R -3-(吡啶基-2)-1,2,4-三嗪与原位生成的取代的芳烃中间体之间的相互作用。根据1,2,5碳原子上两个取代基的性质,反应可提供反需求(ID)的aza-Diels-Alder产品或1,2,4-三嗪环重排(domino)产品作为主要产品。 4-三嗪核或在芳烃部分。根据X射线数据确定了关键产品的结构。基于Diels–Alder过渡态几何的密度泛函理论(DFT)研究,提出了芳烃性质对1,2,4-三嗪转化方向的影响。
Abstract A series of new coppercomplexes have been synthesized and completely characterized by pivotal analytical techniques. The coordination geometry around copper(I) complex was best described as distorted tetrahedral geometry. The binding of bovine serum albumin with Cu(I) complexes are also been investigated. The Stern–Volmer analysis on quenching data exhibits the presence of the static quenching

The reaction between 5-R-6-R1-3-(2-pyridyl)-1,2,4-triazines and benzyne generated in situ in toluene under reflux results in the formation of 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles 3 in up to 60% yields instead of the expected 3-R-4-R1-1-(2-pyridyl)isoquinolines 2. The crystal structure of product 3c and the proposed mechanism for the formation of 3 are reported.

We have developed an efficient synthesis of new cadmium(II)-containing complexes based on poly(aza) arene-annelated 2,2'-bipyridines. All the complexes were characterized by X-ray structural analysis. The influence of the type of the ligand at the structural properties of the complexes has been studied. (C) 2016 Elsevier Ltd.
