The catalytic potential of copper(I)-exchanged zeolites was evaluated in the Ullmann-type synthesis of diaryl ethers. Among four investigated zeolites (i.e., USY, MOR, β, and ZSM5), Cu(I)-USY was the best catalyst and proved efficient under ligand-free conditions in toluene at 120 °C. Cu(I)-USY was also easy to recover and was recyclable up to five times without significant loss of activity.
研究了铜（I）交换沸石在Ullmann 型二芳基醚合成中的催化潜力。在所研究的四种沸石（USY、MOR、β 和 ZSM5）中，Cu（I）-USY 是最好的催化剂，在无配体条件下于 120°C 的甲苯中表现出高效。Cu（I）-USY 易于回收，可重复使用多达 5 次，活性损失不明显。
