Exempel på hur man kan använda DIAZO i en mening

• Examples of typical reproduction methods include: diazo (blueline), electrostatic (xerographic), photographic, laser, and ink jet.
• It is a reagent for conversion of amines into diazo compounds, which are key precursors to many dyes, such as diazo dyes.
• A quirk of diazo blueline prints is that with continued exposure to ultraviolet light, either from natural sunlight or from typical office fluorescent lighting, a blueline copy can fade over months (indoors) or just days (outdoors), becoming illegible.
• By means of their diazo derivatives can be de-amidated, yielding in this way azonium salts; consequently they may be considered as amidated azonium salts.
• It is a non-fluorescent, relatively thermostable lysochrome (fat-soluble dye) diazo dye used for staining of neutral triglycerides and lipids on frozen sections and some lipoproteins on paraffin sections.
• The Barton–Kellogg reaction is a coupling reaction between a diazo compound and a thioketone, giving an alkene by way of an episulfide intermediate.
• Diazodinitrophenol (DDNP) was the first diazo compound produced; it was subsequently used to make dyes and explosives.
• Initial studies which demonstrated the transient intermediacy of the seven-, six- and five-membered cycloalkynes relied on trapping of the high-energy alkyne with a suitable reaction partner, such as a cyclic dienes or diazo compounds to generate the Diels–Alder or diazoalkane 1,3-dipolar cycloaddition products, respectively.
• It condenses with ketones and aldehydes to form hydrazones, which can be further transformed into reactive intermediates such as diazo compounds or carbenes.
• For symmetrical triazenes derived from primary amines, partial diazotization gives a mixture of the original amine and its diazo derivative that then couple with each other.
• Certain diazo compounds, such as diazomethane, can react with olefins to produce cyclopropanes in a 2 step manner.
• The ylide is prepared in situ by reaction of the diazo compound ethyl diazomalonate with a sulfide catalyzed by dirhodium tetraacetate in refluxing xylene.
• APC catalyzes many organic reactions, such as cross-coupling, nucleophilic addition to dienes, and decomposition of diazo compounds to reactive carbenes.
• Carbenes prepared by other methods such as diazo compounds, might exhibit properties better attributed to the diazo compound used to make the carbene (which mimic carbene behaviour), rather than to the carbene itself.
• Azaserine is a naturally occurring serine derivative diazo compound with antineoplastic and antibiotic properties deriving from its action as a purinergic antagonist and structural similarity to glutamine.
• This compound is converted to the diazo ketone 5 by deprotonation (using acetic acid and sodium methoxide) and reaction with tosyl azide.
• as a Lewis acid for Diels Alder reactions, for cyclopropanation of alkenes with diazo reagents, and as a Lewis Acid in Meinwald Rearrangement reactions on Epoxides.
• histochemical characteristics of enterochromaffin cells using advanced techniques, not normally used at that time, such as diazo reactions, Wood's lamp and fluorescence microscopy.
• An example of a transition metal-catalyzed cyclopropanation is a synthesis of tranylcypromine, in which the sodium salt of benzaldehyde tosylhydrazone is converted to a rhodium metal carbene through the diazo intermediate.
• Lomaiviticins are aromatic polyketides in the angucycline family and share a diazo group similar to kinamycins.
