One aspect of the present invention relates to novel reaction conditions that allow the efficient synthesis of diaryl ethers from arenes bearing a leaving group and arenols under relatively mild conditions. Another aspect of the present invention relates to the dramatic effects of acidic activators on Ullmann-type couplings involving electron-poor and/or relatively insoluble substrates.
本发明的一个方面涉及新颖的反应条件,允许在相对温和的条件下从带有离去基团的
芳烃和芳醇中高效合成二芳基醚。本发明的另一个方面涉及酸性活化剂对涉及电子贫乏和/或相对不溶性底物的乌尔曼型偶合反应的显著影响。
