Pyridazines. 67. Homolytic phenylation of some azolopyridazines was written by Furlan, A.;Furlan, M.;Stanovnik, B.;Tisler, M.. And the article was included in Monatshefte fuer Chemie in 1974.Synthetic Route of C6H5N3 This article mentions the following:
Homolytic phenylation of imidazopyridazines I (R = H, Ph, R1 = H; R = H, Ph, Me, R1 = Cl), triazolopyridazines II (R = H, Me, Ph, R1 = H, Cl), and III (R1 = H, Cl) with Bz2O, with or without PhCl, occurred preferentially at the 8-position. I also yielded 3-Ph derivatives II (R = H) also gave 8-Ph and 3-Ph derivatives, whereas II (R = Me, Ph) was substituted at the 8-position and then at the 7-position. III were phenylated only at the 8- and 7-positions. In the experiment, the researchers used many compounds, for example, Imidazo[1,2-b]pyridazine (cas: 766-55-2Synthetic Route of C6H5N3).
Imidazo[1,2-b]pyridazine (cas: 766-55-2) belongs to pyridazine derivatives. Pyridazines is a six-membered nitrogen-containing significant heterocycle. It has received considerable interest because of its useful applications as natural products, pharmaceuticals, and various bioactive molecules. Pyridazine compounds have attracted interest in various fields like medicinal, industrial, and agricultural research as they are used for numerous biological activities and other applications.Synthetic Route of C6H5N3
