Of common reagents

The concentration will not be exactly 0.100 M, because the reagent is not exactly 12.1 M. A table inside the cover of this book gives volumes of common reagents required to make 1.0 M solutions. 

This table provides a summary of the common tests for cations, primarily in aqueous solution. The cations are grouped according to the usual convention of reactivity to a set of common reagents. Abbreviations in the table are as follows ... 

Several fluorous counterparts of common reagents have been reported and many of these are also commercially available. Of some interest is the development of fluorous Mitsunobu reagents. A first generation fluorous DEAD reagent was found to have poor reactivity when difficult Mitsunobu reactions were encountered it has since been replaced with two enhanced, second-generation reagents, (1) and (2), for use in parallel or sequential fluorous chromatography and rapid F-SPE isolation, respectively. 

Sometimes, to prove the professionalism and particularness of my fictitious company, I would specify my desire for serious forms of common reagents and solvents. 

For the actual run, stock solutions of common reagents and building blocks must be prepared, and the solid support or solid-supported reagents dispensed into the appropriate reaction vessels (rvs). The reactions must be set up under the proper conditions, run, and subsequently worked up in an appropriate manner. This is followed by optional purification steps and, finally, isolation of the product For all of these steps, equipment is available that helps to achieve high throughput...

The reductive removal of either an alcoholic or ketonic function can be effected by treatment of the alcoholate or enolate anion with tetramethyldiamido-phosphochloridate [(MejNljPOCl] to form the ester, followed by reduction with lithium-ethylamine [e.g. (129)—+ (131)]. Diethylphosphochloridate can be used similarly. The reactions are applicable to primary, secondary, or tertiary alcohols the intermediate esters are stable to a variety of common reagents.

Classification of common reagents used for substitution/ elimination. 

Allan Watson explored the substrate and solvent specificity of a range of common reagents for amide bond formation and reductive amination with a particular view to exploring alternatives to dichloromethane and dimethylformamide. Charts highlight which substrates, solvent and reagents are compatible. 

The chemistry of this group of Nuphar Alkaloids was not well known till now since the system has been shown not to be very reactive to most of common reagents, which usually are used for transformations and degradation of an alkaloid system...
