摘要：

13-Cyclodextrin-stabilized Cu nanoparticles were prepared from CuSO4 <middle dot> 5H2O using sodium hydroxymethanesulfinate (rongalite) as the reducing agent and 13-cyclodextrin as the stabilizing agent. This nanocatalyst showed good catalytic activities in the C-O coupling of phenols with 2-bromopyridine providing 2-aryloxypyridines in moderate to good yields. The catalyst can be recovered and reused five times with slight decrease in its activity.
