		Degradation of Alkyl Ethers, Aralkyl Ethers, and Dibenzyl Ether by Rhodococcus sp.
		Halogenated alkyl ethers are also used in anesthetics and polymer syntheses, but their use is controversial, because the cytochrome P450-catalyzed degradation metabolites, e.g., trifluoro-substituted aldehydes, are reactive with proteins and cause acute hepatic and immunological disease (6).
		Diethyl ether and dibenzyl ether were oxidized eventually by induction with either diethyl ether or dibenzyl ether, suggesting the involvement of the same enzyme in the oxidation of the two compounds.

		This study shows that the halogenated ether anesthetics isoflurane, sevoflurane, and enflurane are also bound to the hydrophobic core of the four-[alpha]-helix bundle, using isothermal titration calorimetry.
		Because halogenated ether anesthetics are currently used primarily in the United States and Europe it is of interest to determine whether these molecules can also associate with the current four-[alpha]-helix bundle design.
		In contrast to halothane and chloroform, these halogenated ether anesthetics are not efficient quenchers of tryptophan fluorescence, precluding the use of this spectroscopic approach (Johansson et al., 1995) to monitor anesthetic binding.

	Chemical Reactivity
		Ether solvents such as THF and DME (dimethoxyethane or glyme) are commonly used for alkylations because they are inert to strong base and dissolve enolate salts more effectively than hydrocarbons.
		The difunctional ether DME (dimethoxyethane) is especially effective at solvating cations; and this fact has led to the preparation of cyclic polyethers, known as crown ethers, which are extraordinarily powerful solvating agents.
		Once a pure silyl ether isomer is in hand, it may be used to generate the corresponding lithium enolate in the manner shown.

		Halogenated benzyl ethers are protecting groups which are stable to a range of reaction conditions.
		Here, we describe a set of halogenated benzyl ether protecting groups for hydroxyl, amine, carboxylate and phosphate functionalities which may be selectively removed by a two-step method, comprising the steps of palladium catalyzed amination, followed by treatment with a Lewis acid or oxidation.
		Halogenated benzyl moieties in the form of carbamates are useful as amine protecting groups and will also serve well for the masking of phosphate and carboxylic acids.

	Prediction of vapour pressures for halogenated diphenyl ether congeners from molecular descriptors
		The purpose of the present investigation was to characterise halogenated diphenyl ethers using computationally derived descriptors, and to develop calibration models for the vapour pressure from published experimental data.
		The type and number of halogen atoms in the molecule were the main factors influencing the vapour pressures of halogen substituted diphenyl ethers, but the variations in substitution pattern was also shown to be a significant factor.
		The estimated prediction errors are expected to be within the reported boundaries when the models are applied to new objects within the same molecular descriptor space, and model predictions can hence extend the current database of experimental values.
