A new and efficient protocol for the C-N cross-coupling of aryl halides with heteroaromatic amines using lanthanum(III) oxide (10 mol%) as a recyclable catalyst, N,N’-dimethylethylenediamine (DMEDA) (20 mol%)as a ligand, and potassium hydroxide (KOH) as a base in DMSO at 110 °C has been developed. This inexpensive catalytic system is highly effective towards the amination of aryl halides with various nitrogen nucleophiles and is significantly tolerant towards other functional groups in the substrates. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Recommanded Product: 1843-21-6).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Recommanded Product: 1843-21-6
