A Rh(III)-catalyzed C-H ortho-mono-olefination of aryls directed by 7-azaindoles was reported, this method opens up a novel pathway to synthesize complex 7-azaindole derivatives and interestingly, we obsereved an intramolecular cascade...
Diazo compounds play an important role as a coupling partner in the synthesis of unique π-conjugated 7-azaindole derivatives via rhodium(III)-catalyzed double C–H activation/cyclization.
A facile and convenient strategy for the assembly of N-arylated heterocycles has been demonstrated using a MnCl2.4H2O/trans-1,2-diaminocyclohexane catalyst and K3PO4 as the base in water.

An efficient and convenient bimetallic MnF2/CuI catalyst in combination with trans-1,2-diaminocyclohexane has been developed for the cross-coupling of nitrogen heterocycles with aryl halides in water at moderate temperature. A variety of nitrogen nucleophiles including pyrazole, 7-azaindole, indazole, indole, pyrrole and imidazole afforded the corresponding products in moderate to good yields (up to
