Shaken, not stirred: a schools test for aldehydes and ketones

A schools test for aldehydes and ketones in water at room temperature using test tubes has been developed in this laboratory using either phenylhydrazine hydrochloride or phenylhydrazine hydrochloride with NaOAc . 3H2O. The role of one equivalent of a strong or weak acid which catalyses the reaction is discussed.

Rhodium(III)-catalyzed c-h activation and indole synthesis with hydrazone as an auto-formed and auto-cleavable directing group

An efficient, practical, and external-oxidant-free indole synthesis from readily available aryl hydrazines was developed, by using hydrazone as a directing group for RhIII-catalyzed C-H activation and alkyne annulation. The hydrazone group was formed by in situ condensation of hydrazines and Ci￡O source, whereas its N-N bond was served as an internal oxidant, for which we termed it as an auto-formed and auto-cleavable directing group (DGauto). This method needs no step for pre-installation and post-cleavage of the directing group, making it a quite easily scalable approach to access unprotected indoles with high step economy. The DGauto strategy was also applicable for isoquinoline synthesis. In addition, synthetic utilities of this chemistry for rapid assembly of π-extended nitrogen-doped polyheterocycles and bioactive molecules were demonstrated. Copyright

The title hept-1-enitol (2) reacted with aldehyde methyl(or phenyl)hydrazones in refluxing methanol or butyl acetate to give 1-methyl(or phenyl)-5-(penta-O-acetyl-D-galcto-pentitol-1-yl)pyrazoles in good (for 1-methylpyrazoles) or moderate yields (for 1-p

ALKALINE ISOMERIZATION OF PHENYLHYDRAZONES TO ALKYLPHENYLDIIMIDES

When solutions pf phenylhydrazones in tri- or tetraethylene glycol are heated in the presence of the corresponding sodium glycolate, they undergo isomerization to alkylphenyldiimidates.There is a marked decrease in the isomerization rate in the transition from the hydrazones of aldehydes to the hydrazones of ketones.With the phenylhydrazones of ketones the reaction takes place almost unambiguously, but in the case of hydrazones of aldehydes it is complicated to an appreciable extent by side processes such as indolization and aminonitrile cleavage.
