, p. 3113 - 3118 (2007/10/03)
A simple and efficient method has been developed for the synthesis of phenolic ethers using room-temperature ionic liquid, not only as solvent but also as promoter. Ionic liquid was recycled and subsequently reused without any loss of the product. Copyright Taylor & Francis, Inc.

Taniguchi, Hisaji,Otsuji, Yoshio,Nomura, Eisaku
, p. 3563 - 3568 (2007/10/03)
The formation of ethers was catalyzed by 5,11,17,23,29,35-hexa-p-t-butyl-37,38,39,40,41,42-hexakis(3,6,9-trioxadecyloxy)calixarene (1).It was found that the calixarene-catalyzed reaction of phenol with benzyl bromide in the presence of KOH in CH2Cl2 yields only the O-alkylated product and this reaction proceeds according to Michaelis-Menten type kinetics.The calixarene 1 also catalyzed the reactions of phenols with dichloromethane and 1-chloro-4-nitrobenzene.

5,11,17,23,29,35-Hexa-p-tert-butyl-37,38,39,40,41,42-hexakis-(3,6,9-trioxadecyloxy)calixarene catalyzes the formation of an ether and bisphenoxymethanes through the Williamson synthesis.
Kinetics of Reaction between Methylene Iodide and Phenoxide Ion
Panigrahi, G. P.,Sinha, T. K.
, p. 1065 - 1067 (2007/10/02)
The kinetics of reaction between methylene iodide and phenoxide ion have been studied in 50 percent (v/v) aq.DMSO, aq.DMF and aq. acetone.The activation parameters for the reaction have been determined in aq.DMSO.The reactivity pattern has been rationalized in the light of Hammett's linear free energy relationship.The reaction essentially involves attack on the oxygen atom of phenoxide ion.The validity of the isokinetic relationship has been examined using Exner's method.
