Combined C-H functionalization/C-N bond formation route to carbazoles.

摘要: A new method in which a series of substituted carbazoles is efficiently produced by the combination an amide and arene described. The key feature this palladium-catalyzed tandem directed C−H functionalization arylation. tolerates substitution on either ring biaryl substrates, products can be assembled simple two-step protocol from readily available reagents. Pd(0) species generated are reoxidized to Pd(II) presence Cu(OAc)2 atmosphere oxygen.
