AC — nF F at unit activities, it follows that the reactions will occur spontaneously in the reverse direction to that written when E"" is negative, i.e. hydrazine is oxidized by the reagents listed. 

The reagents listed above can be applied to the reduction of many other ions in addition to Fe3+, and there are also a number of other substances which can be employed as reducing agents thus for example hydroxylammonium salts are frequently added to solutions to ensure that reagents do not undergo atmospheric oxidation, and as an example of an unusual reducing agent, phosphorous (III) acid may be used to reduce mercury(II) to mercury(I) see Section 10.129.

If iV-formyl peptide chemoattractants conjugated with fluorochrome are purchased from a commercial source, the reagents listed in Subheading 2. referencing this note are not needed. Although this chapter has focused on iV-formyl peptides, other chemoattractants, such as complement-derived C5a, have also been fluorescently labeled and evaluated in flow cytometric assays (9-11). 

The reagents listed in Subheading 2. referencing this note are not needed if a chemotaxis assay is not performed. 

The correlation tables on the following pages show how the main types of compounds are reduced to various products by different reducing agents. The tables list only the reactions contained in this book (with exceptional cases omitted). If a reagent for a certain conversion is not listed, that does not necessarily mean that it cannot accomplish a particular reduction. Reagents listed in parentheses apply only under special conditions or are used exceptionally. 

Write the equations for the chemical reactions involved. State what surface groups will be labeled by each reagent. List special advantages of each of these reagents. 

Jones reagent is used to oxidize the aldehyde here to an acid. In general only the first two reagents listed in the Tips oxidi/e aldehydes to acids. TPAP can be used for oxidation of alcohols to aldehydes, ketones, or acids. The others are used for oxidizing alcohols to aldehydes or ketones.27... 

Among the other reagents listed, activated Mn02 is specific for the oxidation of allylic and ben/ylie alcohols.22 KM11O4 is used for the oxidation of alkenes to diols.23 Ceriv(lV) ammonium nitrate (CAN) accomplishes oxidative cleavage of the PMB protecting group. 

All the reagents listed can be used to cleave trimethylsilyl groups from acetylenes fluoride, potassium carbonate under basic conditions in methanol, or silver nitrate/potassium cyanide.9 With the third method advantage can be taken of the fact that the later transition metals (e.g., copper or silvei) complex readily with acety-lides. Workup with concentrated potassium cyanide solution causes compound 32 to be cleaved tu alkyne 33. In this way silylated a -kynes can be deprotected in the presence of 0-silyl groups. 

B-ll. Ethylbenzene is treated with the reagents listed, in the order shown.

The following section gives a summary for the preparation of the major spray reagents listed in the previous section (Spray Reagents in Thin-Layer Chromatography). Refer to the original literature for any reagents not listed here.1 4... 

The silylamide route is also transferable to lanthanide(II) chemistry. However, now steric effects are of minor importance due to the enhanced steric flexibility of Ln(II) amides. Eu(II) and Yb(II) silylamides are accessible to exchange reactions for all reagents listed in Scheme 6. For example... 

In Westheimer s original photoaffinity labeling experiment, diazoacetyl-chymotrypsin was photolysed. Later, Westheimer s group made the improved diazo reagents listed in Table 3.1. 

Several control experiments have been suggested to confirm that hydrophobic reagents do label from within the lipid bilayer (Bercovici et al. 1978 Bayley and Knowles, 1980). Even though the reagents listed in Table 6.1 have been thoroughly tested and their virtues and limitations described, the wise investigator will repeat at least some of the controls described here with his system.

For the oxidation of primary or secondary alcohols on a laboratory scale, one usually employs one of the reagents listed in Table 17.5. The reactivity of these six reagents toward alcohols and aldehydes can be summarized as follows ... 

All reagents listed in Table 17.5 can be used for the oxidation of secondary alcohols to... 

Show the products, including regiochemistry and stereochemistry, resulting from the addition to alkynes of all of the reagents listed in this chapter. These reagents include HX, X2, Hg2+/H+/H20, disiamylborane, and H2. (Problems 11.32 and 11.33)... 

Shake in a small test tube ca 0,2g of ground unknown subst with ca 5ml of CC1. and allow to stand for 5mins. If the sample is completely sol it is usually TNT. Confirm its presence by treating the soln with one or more colori metric reagents listed in Charts A B. If the sample is only partially sol in CC14, remove the liquid portion and test it for TNT XVIX. Treatment with Acetone. If the subst is not completely sol in CC14 proceed as follows ... 

Of the reagents listed in Table 8.1, dialkyllithiocuprates stand out because of their unique ability to participate in 1,4-addition reactions. Such reactions, also known as conjugate additions, are generally referred to as Michael additions. This name reaction is illustrated in Scheme 8.16 with the reaction of dimethyllithiocuprate with methyl vinyl ketone.
