Technical Notes:

1. L igand used with Cul to form a general and highly efficient catalyst for the N-amidation of aryl and

heteroaryl iodides, bromides and in some cases, unactivated aryl chlorides. The catalyst system is also used for the N-arylation of indoles.

2.L igand used for the N-Arylation of pyrroles, pyrazoles, indazoles, imidazoles and triazoles.

3.L igand used for the -arylation of 4-aminophenols.

4. L igand used for the N-arylation of primary sulfonamides .

5. L igand used for the Cu-catalyzed chloride/iodide and bromide/iodide exchange of aryl halides.
