18640-74-9, An article , which mentions 18640-74-9, molecular formula is C7H11NS. The compound – 2-Isobutylthiazole played an important role in people’s production and life.
The reactivity of positions C9 and C10 of 9- or 10-bromophenanthrenes in palladium-catalyzed direct heteroarylations was investigated. A wide variety of heteroarenes such as thiazoles, (benzo)thiophenes, (benzo)furans, pyrroles, selenophenes or imidazopyridazines was successfully introduced at phenanthrene C9-position via palladium-catalyzed direct arylations, using 0.5?0.1 mol-% of phosphine-free Pd(OAc)2 catalyst. Then, C10-bromination of the 9-heteroarylated phenanthrenes, followed by a second palladium-catalyzed direct heteroarylation gives access to symmetrical and non-symmetrical 9,10-di(heteroaryl)phenanthrenes.
