The aryl-triazene, as an extremely useful and versatile organic synthesis midbody, can be extracted from the aromatic amines in a simple way. This paper mainly describes the arylation reaction between palladium catalysis aryl-triazene and indole and azole compounds; the cyclization reaction between rhodium catalysis aryl-triazene and N-methoxybenzamide; while we also design a cross-coupling reaction of palladium catalysis aryl-triazene with indole, and filter catalysts, solvents and additives to contribute the best experiment conditions and a good harvest in the end. The results deduced in the paper show that aryl-triazene attributes to a useful organic synthesis midbody which actively involves in coupled reaction with indole-2.
