Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
Hydrazones are converted to azines when used in the preparation of 3,5-disubstituted 1H-pyrazoles, [11] a reaction also well known using hydrazine hydrate. [12] [13] With a transition metal catalyst, hydrazones can serve as organometallic reagent surrogates to react with various electrophiles. [14]
[citation needed] These highly soluble versions of Lawesson's reagent are created by the reaction of P 4 S 10 with aryl ethers which are different from anisole. For instance butoxybenzene and 2-tert-butylanisole have both been reacted to form more soluble thionation reagents of the 1,3,2,4-dithiadiphosphetane 2,4-disulfide class.
According to their properties, cations are usually classified into six groups. [1] Each group has a common reagent which can be used to separate them from the solution.To obtain meaningful results, the separation must be done in the sequence specified below, as some ions of an earlier group may also react with the reagent of a later group, causing ambiguity as to which ions are present.
Structure of a rare monomeric boron hydride, R = i-Pr. [4] The most-studied class of organoboron compounds has the formula BR n H 3−n. These compounds are catalysts, reagents, and synthetic intermediates. The trialkyl and triaryl derivatives feature a trigonal-planar boron center that is typically only weakly Lewis acidic.

The Hinsberg reaction is a chemical test for the detection of primary, secondary and tertiary amines.The reaction was first described by Oscar Hinsberg in 1890. [1] [2] In this test, the amine is shaken well with the Hinsberg reagent (benzenesulfonyl chloride) in the presence of aqueous alkali (either KOH or NaOH).
