2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3) belongs to nitriles. Nitrile carbon shifts are in the range of 115–125 ppm whereas in isonitriles the shifts are around 155–165 ppm. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Synthetic Route of C15H15N3

Oxidation of hexamethylbenzene and 2,3,4,5,6-pentamethylbenzyl cation in fluorosulfonic acid was written by Rudenko, A. P.;Zarubin, M. Ya.;Fedorova, E. M.. And the article was included in Zhurnal Organicheskoi Khimii in 1985.Synthetic Route of C15H15N3 The following contents are mentioned in the article:

Oxidation of hexamethylbenzene (I) in HSO3F-PbO2 involved the conversion of protonated I to 2,3,4,5,6-pentamethylbenzyl cation, which underwent further oxidation to give products such as II and III. This study involved multiple reactions and reactants, such as 2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3Synthetic Route of C15H15N3).
