Yatsyuk V. Dediazonation of aromatic bisdiazonium salts in conditions of Sandmeyer and anionarylation reaction

Dissertation is devoted to the study of the interaction of aromatic diazonium salts with different strengths nucleophiles in conditions of Sandmeyer and anionarylation reaction. The main regularities of catalytic and non-catalytic dediazonation reactions of bisdiazonium tetrafluoroborates based on benzidine, phenylenediamines and their derivatives in the presence of chloride, bromide, thiocyanate, and N,N-diethyldithiocarbamate anions were found. In the case of N,N-diethyldithiocarbamate anions the yields of related products in non-catalytic conditions higher than the catalyst, due to the formation of more stable copper complexes with these anions compared to thiocyanate.
