An efficient tandem oxidative-protection reaction of benzylic alcohols to corresponding arylhydrazones and oximes

A mild and efficient one-pot synthesis of hydrazones and oximes from the reaction of the oxidation product of benzyl alcohols and phenols by 3,6-bis(triphenylphosphonium)cyclohexene dichromate with phenylhydrazine, 2,4-dinitrophenylhydrazine, and hydroxylamine is described.

Addition of Semidione Radicals to Arenediazonium Ions: Synthesis of 1,1-Diacyl-2-arylhydrazines

The α-dicarbonyl compounds 1 are selectively reduced to semidione radicals 2 by aqueous Ti3+, via inner-sphere electron transfer (ET).When an equimolar amount of an arenediazonium salt (3) is present, 2 adds to the nitrogen-nitrogen triple bond of 3 to afford the intermediate azo radical cation C, which, depending on the nature of the para substituent of the N-phenyl ring, undergoes rearrangement to a 1,1-diacyl-2-arylhydrazine (4) or preferentially reduction to a hydrazone (5).A mechanism that accounts for both the rearrangement and the substituent effects that are observed is proposed.

About the Photochromic and Thermochromic Effect of Benzil Phenylhydrazones

Benzil phenylhydrazone 1 synthesized from benzil and phenylhydrazine possesses s-trans-E configuration detected by means of quantum chemical calculations and its spectral data.Upon irradiation a photochromic process proceeds with λ-shift Δλ ca. 80nm.The p

Oxidation of Arylhydrazones by Thallium(III) Acetate - A Kinetic Analysis of Structural Effect on the Oxidation

The kinetics of oxidation of the phenylhydrazones of several substituted benzaldehydes by Tl(III) has been studied in aqueous acetic acid in the presence of initially added sodium chloride (0.05M).The reaction exhibits a first order dependence on and and is retarded by added sodium chloride and sodium acetate.The reaction is accelerated by electron-releasing substituents in the benzaldehyde moiety while electron-withdrawing substituents retard the reaction.The reaction data obey Hammett relationship with ρ = -1.62.Electron-withdrawing groups in the phenylhydrazine moiety also reduce the reaction rate (ρ = -2.66).The major product of the reaction is the cis-monohydrazone of benzil.
