The thiophene synthesis described herein is related to the synthesis in solution reported by Laliberte, and Medawar4 but differs in some aspects from the procedure in homogeneous phase. Laliberte and Medawar succeeded in obtaining aminothio-phenes in a one-pot reaction from acceptor-substituted acetonitriles, isothiocyanates, a-haloketones, and sodium ethoxide. In contrast to their procedure, solid-phase S-alkylation of the intermediate thioamides under basic conditions led to the formation of product mixtures. We obtained pure aminothio-phenes only when conducting the S-alkylation under neutral or slightly acidic conditions. 

Catalytic epoxidation of olefins (typical procedure) Solid catalyst (1 g) prepared from XAD-2 resin is stirred with 20 mL of 1.0 M cyclohexane and 1.0 M H2O2 in t-BuOH or dioxane at 60°C for 24 h. Cyclohexenoxide is obtained in a quantitative yield. 

The tris(ethylenediamine)ruthenium(III) species is obtained by oxidation of [Ru(en)3]2+ with, for example, iodine4 or bromine.6 The oxidizing agent and conditions employed must be chosen carefully to avoid further oxidation of the ethylenediamine ligand to coordinated diimine.7 In the present procedure solid silver anthranilate is used to oxidize [Ru(en)3] [ZnCl4], and [Ru(en)3] Cl3 is isolated. In this heterogeneous procedure the desired [Ru(en)3]Cl3 is the only soluble product and can easily be separated from the insoluble silver, silver chloride, and zinc dianthranilate. Other less soluble [Ru(en)3]3+ compounds can be obtained easily from the soluble chloride. 

One major issue underlying salivary peptidome characterization is peptide quantification. While some quantitative methods developed for proteome studies were inherited, peptidome analysis has its own quantification traits. Direct profiling with MALDI-MS or SELDI-MS has been one of the most widely used approaches for peptidome despite its limitations. For instance, Zhang el al. (32,44) used magnetic beads combined with MALDI-MS for saliva profiling in response to orthodontic procedures, solid foods, and teeth...

The apparatus employed for the investigation is based on a modified version of the dew and bubble-point method of phase-boundary determination. By altering the standard procedure, solid-liquid-vapor and solid-vapor equilibria data can be determined along with the vapor-liquid data in the same basic apparatus used for dew and bubble-point measurements. The method presented here is a slight variation of the method presented by Kurata and Kohn [ ] and similar to that of Donnelly and Katz p]. 

The sensitivity of this method is comparable to, or better than, those of LC separation techniques for urine. The technique overcomes the limitations of and obstacles in conventional methods such as the use of expensive and frequently contaminated organic solvents and of tedious and time-consuming sample preparation [e.g., derivatiza-tion procedure, solid-phase extraction (SPE)] with satisfactory levels of sensitivity. 

Landspreading In this procedure, solids from the reserve pit (and potentially other solids from production) are broken up and thinly applied to soil, and tilled to mix the waste and soil. In theory, volatile components evaporate off, metal ions bind to the clay, and heavy organic components are broken down by biological activity. States regulate this practice differently.

With gaseous amines, the addition techniques mentioned under acyl halide reactions may be applied. With liquid amines, the preparation of A-ethylperfluorobutyramide may serve as a model synthesis. As to final purification procedures, solid amides may be recrystallized (alcohol, alcohol-water, petroleum ether, etc. are typical solvents), or, in many cases, distilled under reduced pressure. Liquid amides are best purified by distillation.
