Structural (X-ray), spectral (FT-IR and Raman) and quantum chemical investigations of a series of 6-benzylaminopurine derivatives was written by Cajan, Michal;Travnicek, Zdenek. And the article was included in Journal of Molecular Structure in 2011.Name: 2,6-Dichloro-9-isopropyl-9H-purine This article mentions the following:
The structural and spectroscopic properties of 6-(2-methylbenzylamino)purine 1, 6-(4-methylbenzylamino)purine 2, 6-(3,4-dimethoxybenzylamino)purine 3, 2-chloro-6-(3-bromobenzylamino)-9-isopropylpurine 4 and 2-chloro-6-(3,4-dichlorobenzylamino)-9-isopropylpurine 5 have been investigated by means of single crystal X-ray diffraction anal., FT-IR and Raman spectroscopy, and quantum chem. calculations, where HF, DFT, RI-MP2 and MP2 methods in combination with the cc-pVDZ basis set have been used. The theor. obtained structural as well as spectral parameters have been compared with those exptl. obtained. One of the unusual structural features is the finding that the electroneutral form of 6-(2-methylbenzylamino)purine 1 is protonated at the N7 position of the purine ring, which is not a typical protonation site for N9-unsubstituted adenine derivatives In the experiment, the researchers used many compounds, for example, 2,6-Dichloro-9-isopropyl-9H-purine (cas: 203436-45-7Name: 2,6-Dichloro-9-isopropyl-9H-purine).
2,6-Dichloro-9-isopropyl-9H-purine (cas: 203436-45-7) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Name: 2,6-Dichloro-9-isopropyl-9H-purine
