A general and efficient protocol for the synthesis of biaryl ethers from aryl silyl ethers using Cs2CO3

A general and efficient one-step procedure has been developed for the synthesis of biaryl ethers via direct coupling of electron-deficient arylhalides or aryl triflates to aryl t-butyldimethylsilyl (TBS) ethers using Cs 2CO3. The protocol was also applied to electron-rich arylhalides by addition of a catalytic amount of copper(I) iodide. The reaction is rapid and provides good to excellent yields.
