Cesium fluoride-Celite: A solid base for efficient syntheses of aromatic esters and ethers
Coupling reactions of a number of aromatic and heteroaromatic phenols with alkyl, acyl or benzoyl halides in acetonitrile with cesium fluoride-Celite are described, demonstrating that this reagent provides an efficient, convenient and practical method for the syntheses of aromatic esters and ethers.

Synthesis of aromatic ethers without organic solvent and inorganic carrier under microwave irradiation
A simple, rapid and efficient procedure for the synthesis of aromatic ethers via microwave irradiation without any organic solvent and inorganic carrier is reported.
Electron Apportionment in Cleavage of Radical Anions. 1. Nitro-Substituted Benzyl Phenyl Ethers
The radical anions of 4-nitrobenzyl phenyl ethers undergo cleavage at least 10E4 times faster than the radical anions of corresponding 4-nitrophenyl benzyl ethers despite a perceived thermodynamic advantage for the latter set of reactions.It is suggested that this results reflects a kinetic advantage for cleavage reactions which take place with regioconservation of spin density.
