CsF–Al2O3 mediated rapid condensation of phenols with aryl halides: comparative study of conventional heating
s. microwave irradiation†
Abstract
Biaryl ethers and thio ethers are formed in high yields by the condensation of phenols and thiophenols with electron-deficient aryl halides using CsF supported on Al2O3 under microwave irradiation in solvent-free conditions.
