Cu(I)/Cu(II)/TMEDA, new effective available catalyst of sandmeyer reaction

Abstract

The system Cu(I)/Cu(II)/N,N,N′,N′-tetramethylethylenediamine is a highly efficient and accessible catalyst of Sandmeyer reaction. The reaction of aryldiazonium salts with chlorides, bromides,, cyanides, and thiocyanates of alkaline metals in the presence of this catalytic system leads to the formation of the corresponding aryl halides, nitriles, and thiocyanates in high yields.
