Abstract
(E)-3-(Dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one was found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 ˚C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.
Key words

General Procedure
All
chemicals were obtained from commercial source and used without
further purification. A stirred suspension of aryl halides (0.5
mmol), azoles or amides (0.5 mmol), CuI powder (0.05 mmol), Cs2CO3 (1.0
mmol), and L5 (0.1 mmol) in MeCN was refluxed
for 12 h (monitored by TLC) under nitrogen. After the mixture was
cooled to r.t., the MeCN was removed in vacuo. The solid was then
extracted with EtOAc (3 × 10 mL), washed
with H2O (3 × 10 mL), and dried
over Na2SO4. After the solvent was removed,
the crude mixture was purified by silica gel column chromatography to
provide the desired product.
