Photochromic Molecular Materials for the Controlled Organization of Nanoparticles
… of polystyrene nanoparticles promoted by bulk azo mass transfer using interferential light illumination will be discussed. For this a variety of different push pull small azo molecules were synthesis and characterized, changing the polarity, hydrophobicity and bulky groups around the azo …

Monitoring for sulfonated azo dyes and their degradation products in industrial and municipal wastewater
Sulfonated azo compounds are one of the most commonly used textile dyes. They pose an environmental problem because they can be difficult to degrade in municipal and industrial treatment systems and can cause effluent wastewaters to violate color standards. Methods were developed to monitor for …

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 …

THE SYNTHESIS AND CHELATION OF SOME AZOPYRIMIDINES
Numerous azo compounds have been shown in the past to have either a stimulating or inhibiting effect on tumour growth* The first recorded observation of the production of tumor-like proliferations was made by Fisher in 1906, who described the atypical epithelial proliferations which re-sulted from …

Medicinal nitro compounds
… a review of the biological properties of nitro compounds. Included in the discussion are those derivatives which have clinically-useful activity and those of a More experimental nature. Some metabolic transformations of nitro compounds are discussed, and the possibility that the toxicity and …

[3+2]-Cycloadditions of Azomethine Imines and Ynolates and Progress Towards a Radical Three-Component Cross-Coupling Reaction
… chapter describes a novel [3+2]-cycloaddition of azomethine imines and ynolates to construct bicyclic pyrazolidinones in high yields and diastereoselectivities. This methodology is the first example in which the azomethine imine acts as a chiral auxiliary to control the cycloaddition. Optically …

The attempted synthesis of precursors of tetraaryldiazoethanes
… useful synthetic methods leading to tetraaryldiazoethanes of the type PhPh<sup>I</sup>Ph<sup>II</sup>CC(N<sub>2</sub>)PH<sup>III</sup> or their precursors. The synthesis of these compounds is of importance since the carbenoid and carbonium ion decomposition of these compounds to …
