โœฆ Synopsis

The presence of cesium carbonate and tetrabutylammonium iodide (TBAI) facilitated efficient O-alkylation of alcohols with alkyl halides, giving rise to the exclusive formation of mixed alkyl carbonates, The cesium effect was also examined comparatively with other alkali carbonates.

Efficient Williamson type O-alkylation of alcohols was developed using cesium bases in the presence of tetrabutylanmaonium iodide (TBAI) and molecular sieves. Various substrates including unreactive primary and secondary alcohols were converted smoothly to the corresponding ethers. Electrophiles use
