Imidazolium Salt Catalyzed para-Selective Halogenation of Electron-Rich Arenes was written by Chen, Jie;Xiong, Xiaoyu;Chen, Zenghua;Huang, Jianhui. And the article was included in Synlett in 2015.Category: chlorides-buliding-blocks This article mentions the following:
A highly para-selective halogenation of arenes bearing coordinating groups in the presence of an imidazolium salt as a catalyst is reported. A series of electron-rich p-haloarenes were prepared in good yields and good to excellent selectivities. We also propose a plausible mechanism for the catalytic reaction. In the experiment, the researchers used many compounds, for example, 2-Chloro-N,N-dimethylaniline (cas: 698-01-1Category: chlorides-buliding-blocks).
2-Chloro-N,N-dimethylaniline (cas: 698-01-1) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Category: chlorides-buliding-blocks
