1,3-Dipolar cycloaddition of diaryldiazomethanes across N -ethoxy-carbonyl- N -(2,2,2-trichloroethylidene)amine and reactivity of the resulting 2-azabutadienes towards thiolates and cyclic amides

1,3-dipolar cycloaddition of diaryldiazomethanes Ar2CN2 across Cl3C-CHN-CO2Et 1 yields Δ3-1,2,4-triazolines 2. Thermolysis of 2 leads, via transient azomethine ylides 3, to diaryldichloroazabutadienes

Tetraethylammonium bromide catalysed phase transfer reaction of potassium superoxide with hydrazones and tosylhydrazones

A variety of hydrazones and tosylhydrazones of carbonyl compounds have been investigated under the mild reaction conditions of potassium superoxide and tetraethylammonium bromide in dry dimethylformamide. As a result, hydrazones are generally transformed to their corresponding azines whereas tosylhydrazones undergo facile fragmentation to give the olefinic products in fairly good yields. The study highlights the use of tetraethylammonium bromide as an efficient and inexpensive catalyst for superoxide studies.

Electrochemical Oxidation of Benzophenone Hydrazones

The anodic oxidation of benzophenone hydrazones (1) was found to give several products, depending upon the electrolysis conditions employed such as electrode material, temperature, and electrolyte composition.For example, the oxidation using a platinum anode at room temperature in LiClO4-MeCN afforded exclusively benzophenone azines (2), whereas in NaOMe-MeOH benzophenone dimethyl acetals (3) were formed as the main products.On the other hand, the oxidation using a graphite anode in refluxing MeOH containing NaOMe gave diphenylmethyl methyl ethers (4), along with diphenylmethanes (5).When the analogous electrolysis was conducted in the presence of methacrylic acid derivatives, corresponding diphenylcyclopropanes (7) were obtained in relatively high yields.

REGIOSELECTIVE MONOALKYLATION OF THE VICINAL cis-DIOL GROUP IN MANNOPYRANOSIDES USING DIARYLDIAZOALKANES-TIN(II) CHLORIDE

Highly regioselective monoalkylations of the cis-2,3-diol group in mannopyranosides can be achieved with diaryldiazoalkanes in the presence of catalytic amounts of tin(II) chloride.With diazo(diphenyl)methane (1), its 4,4'-dimethyl (2) and 4,4'-dichloro (
