Abstract:
The purpose of this investigation was to develop a method that could be used to estimate how damaging sodium ethoxide is to different antigens with respect to immunolabeling when epoxy sections are deplasticized. If we obtain weak labeling for an antigen on deplasticized epoxy sections, this might be caused by the damaging effect of the ethoxide solution. It is therefore interesting to develop a method to check if this really is the reason. Fibrin clots and tissues of human kidney and thyroid were embedded in LR White resin. Some thin sections from these specimen blocks were exposed to sodium

Abstract:
To optimize the ultrastructural localization of immunoglobulin G in corneal crystalloid deposits, we compared a range of antigen unmasking techniques. A human corneal biopsy specimen was fixed in formalin, post-osmicated, and embedded in epoxy resin for electron microscopy. Thin sections were immunogold-labeled for IgG after treatment with sodium ethoxide or sodium metaperiodate. Sections were also treated by heating them at 95 degrees C while they floated on water, 0.01 M citrate buffer (pH 6.0), or sodium metaperiodate. The treatments were applied separately and combined. After labeling, cry

Abstract:
The course and kinetics of the reactions of sulfur mustard, nitrogen mustard and their selected analogues with sodium ethoxide were studied using a gas chromatograph coupled with a mass spectrometer. 2-chloroethyl ethyl sulfide (CEES), a monofunctional analogue of sulfur mustard (HD), bis(2-chloroethyl) ether (BCEE), an oxygen analogue of sulfur mustard, and bis(2-chloroethyl)amine, an analogue of nitrogen mustard HN-3, in which one hydrogen atom remains unsubstituted with a chloroethyl group, were used as imitators of mustards. For the study, the last mentioned compound was given the acronym

Abstract:
The effect of macrocyclic crown ether and cryptand complexing agents on the rate of the nucleophilic displacement reaction of p-nitrophenyl diphenylphosphinate by alkali metal ethoxides in ethanol at 25 °C has been studied by spectrophotometric techniques. For the reactions of potassium ethoxide, sodium ethoxide, and lithium ethoxide, the observed rate constant increased in the order KOEt < NaOEt < LiOEt. Crown ether and cryptand cation-complexing agents have a retarding effect on the rate. Increasing the ratio of complexing agent to base results in a decrease in kobs to a minimum value

The rate of the nucleophilic displacement reaction of p-nitrophenyl benzenesulfonate (1) with alkali metal ethoxides in ethanol at 25 °C has been studied by spectrophotometric techniques. For lithium ethoxide, sodium ethoxide, potassium ethoxide, and cesium ethoxide, the observed rate constants increase in the order LiOEt < NaOEt < CsOEt < KOEt. The effect of added crown ether and cryptand complexing agents was also investigated. Addition of complexing agent to the reaction of KOEt results in the rate decreasing to a minimum value corresponding to the reaction of free ethoxide. Conver

The Dieckmann condensation of methyl [(2-methoxycarbonyl)phenyl]-X-acetates Ia-Ih (X = O, S, SO2, NH, NCH3) initiated by action of magnesium methoxide, ethoxide, isopropoxide and other basic reagents have been studied under various conditions. Whereas magnesium methoxide has comparable efficiency as sodium methoxide and potassium tert-butoxide in syntheses of benzoheterocyclic compounds IIa-IIh, magnesium ethoxide gives the ethyl ester IIb in medium yield, and magnesium isopropoxide is quite inefficient in the condensation reaction.

Kinetic determinations and product studies have been carried out. In ethanol buffered with sodium ethoxide , π-bond participation in the above ester occurs to the extent of 30%; this is raised to 84% when triethylamine is used as the buffering agent. With buffered trifluoroethanol as solvent, π-bond participation in the ester is complete; kunsat/ksat = 920 and a quantitat

Abstract:
The crystal structures of sodium ethoxide (sodium ethanolate, NaOEt), sodium n-propoxide (sodium n-propanolate, NaO n Pr), sodium n-butoxide (sodium n-butanolate, NaO n Bu) and sodium n-pentoxide (sodium n-amylate, NaO n Am) were determined from powder X-ray diffraction data. NaOEt crystallizes in space group P 421 m, with Z = 2, and the other alkoxides crystallize in P4/nmm, with Z = 2. To resolve space-group ambiguities, a Bärnighausen tree was set up, and Rietveld refinements were performed with different models.

Abstract:
This chapter addresses enolate alkylations with alkyl halides. Simple enolates react irreversibly with soft (polarized) electrophiles such as methyl iodide. A new carbon–carbon bond is formed in an S<sub>N</sub>2, which is of considerable synthetic importance. The chapter then looks at enolates derived from simple ketones, simple esters, and β dicarbonyl compounds. If cyclohexanone is treated with ethanolic sodium ethoxide in the presence of methyl iodide, most of the latter reacts with ethoxide ion. However, if the considerably more hindered and slightly more basic t-butoxide is used as base,
