The synthesis and structural characterisation of novel 4- and 5- membered nitrogen heterocycles derived from azoacetates
Azo-drugs are among the earliest fully synthetic chemotherapeutic agents known (Prontosil 1935). However the synthesis and application of phenylazo compounds in the area of medicinal chemistry has largely been restricted to derivatives of primary aromatic amines. This has been due, in the most …

Control of molecular geometries using new photo-electro-switchable azobenzenes
There has been a recent growing interest in azobenzene derivatives because of their ability to isomerize when visible light is absorbed. This unique property allows azobenzenes to undergo reversible conformation change between the trans and cis forms upon absorbing light and slowly thermally …

I. Dissociation and aromatization of a semibenzene. Reactions of triphenylmethyl and methyl isobutyryl radicals. II. The chemistry of alpha- and beta- azo radicals
… The thermolysis of 2,3-dimethyl-2,3-bis(phenylazo)butane (16a) leads exclusively to cleavage of the central C-C bond forming 2-(phenylazo)isopropyl radicals (17a). These radicals recombine to the C-N dimer 19a about 40 times faster than to the more stable C-C dimer 16a. The thermolysis of …

Novel chemical and toxicological studies on textile industry waste streams clean up
… the decolourization of a number of mono- and disazo dyes by UV/oxygen and hydrogen peroxide as a function of initial concentration of dyes, dissolved oxygen and hydrogen peroxide, alkalinity and temperature of solutions were carried out. UV /hydrogen peroxide photochemical treatment was shown to …
