CsF/clinoptilolite was found to be an efficient solid base catalyst for both SNAr and Ullmann ether reactions. A general and efficient one-step procedure was developed for the synthesis of biaryl ethers via direct coupling of electron-deficient aryl halides to phenols using CsF/clinoptilolite. The protocol was also applied to electron-rich aryl halides by addition of a catalytic amount of copper oxide

stocked with molecular diversity and could provide a platform for the discovery of newligand structures. Herein, we describe the use of this approach in combination with highthroughput screening to identify N,N’‐bis(thiophene‐2‐ylmethyl)oxalamide as a ligand that is generally effective for copper‐catalyzed C−O cross‐couplings to prepare both biarylethers as well as phenols under mild conditions.

of aryl fluorides with aryl TBDMS ethers under microwave conditions gave moderate to high yields of the desired products at low catalyst loadings and in short times. In this methodology, electron deficient aryl fluorides possessing substituents, such as nitro, cyano, and ester, were coupled with sterically demanding aryl TBDMS ethers as well as with aryl TBDMS ethers bearing a variety of functionalities
