And the article was published in Chemical Communications (Cambridge, United Kingdom) in 2019. Computed Properties of C7H5ClN2 The author mentioned the following in the article:
Imidazolium-benzimidazolates are readily available conjugated mesomeric betaines, whose carbenic tautomers can form C,Nimine-metal chelates containing amino-functionalized normal or abnormal NHC ligands, depending on the degree of steric congestion. Deprotonation of the amino moiety gives rise to imine-functionalized C,Namido-metal chelates, whose Nimine atom can be easily utilized for the construction of heteronuclear complexes. In the experiment, the researchers used many compounds, for example, 2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1Computed Properties of C7H5ClN2)
2-Chloro-1H-benzo[d]imidazole(cas: 4857-06-1) is an analog of benzimidazole that has been synthesized by Langmuir adsorption isotherm. It is a white crystalline solid that can be dissolved in water and hydrochloric acid. 2-Chloro-1H-benzo[d]imidazole inhibits the growth of herpes simplex virus by acting as a competitive inhibitor for the viral enzyme thymidine kinase, which catalyzes the conversion of thymine to thymidine.Computed Properties of C7H5ClN2
