The conversion of aromatic sulfides to cation radicals and dications in oxidizing media principally sulfuric acid was studied. The structures of the radicals were determined by electron spin resonance spectroscopy. Aromatic sulfoxides in strong acids are converted to the same cation radicals and dications as obtained from the corresponding sulfides. At the same time the aryl rings of the sulfoxide may become hydroxylated. The mechanisms of these reactions have been studied with particular emphasis on heterocyclic compounds such as thianthrene, phenothiazine, phenoxathiin, thioxanthene, and their oxides. The thermal dissociation of a large number of coordination compounds was investigated using the thermal techniques of TGA, DTA, MSA, TMA, X-ray diffraction, and so on. New thermal techniques, such as dynamic reflectance spectroscopy and others, are also described. The photolysis of certain oxalato complexes is also reported. A new type of reaction, thermal matrix reactions, is described and its application to difficult synthetic problems discussed. A four-panel automated research display was fabricated. Author
