## Abstract The effects of pH on the observed rate constants (__k__~obsd.~) and on the solvolytic dediazoniation product distributions of ethanolysis of 2‐, 3‐, and 4‐methylbenzenediazonium ions (2MBD, 3MBD, and 4MBD, respectively) were determined by a combination of spectrophotometric (UV/Vis) and

## Abstract In heterolytic dediazoniations arenediazonium salts form aryl cations. The reaction rates are relatively slow; they depend only to a small extent on the solvent. It is shown that the solvents in which the heterolytic dediazoniation mechanism is predominant have a low nucleophilicity, wh

## Abstract The mechanism of dediazoniation of arenediazonium tetrafluoroborates in 2,2,2‐trifluoroethanol (TFE) is strongly dependent on the concentration of added pyridine. The added base complexes with the diazonium ion and diverts it to a homolytic pathway. Complex formation is indicated by the
