Ullmann-type C-N coupling reaction has been developed for the synthesis of 1-aryl indole derivatives by indoles and aryl halides in the presence of CuI/metformin (CuI/Met) in DMF. This method is very easy, rapid, and high yielding reaction for the synthesis of 1-aryl indoles. In particular, the metformin, which is used as ligand, is inexpensive and nontoxic that is considered to be relatively environmentally benign. (C) 2014 Elsevier Ltd. All rights reserved.

A highly efficient copper(I)-catalyzed N-arylation of azaheterocycles with various aryl halides is reported. The N-arylation reaction can be carried out using as low as 0.5 mol% of (Cu(I)OTf)(2)center dot PhH and 1.0 mol% of 4,7-dichloro-1,10-phenanthroline as the ligand. Furthermore, cheap and stable copper precursors like Cu(I)I and Cu(II)(OAc)(2)-H2O and the cheap and mild base K2CO3 can be used. (c) 2005 Elsevier Ltd. All rights reserved.
