P-Nitrobenzenediazonium borofluoride

B. Reactions with p-nitrobenzenediazonium borofluoride. All mixtures contained 0.2 g. of the diazonium salt in 100 ml. of O.liV hydrochloric acid containing 6 ml. of acrylonitrile, but no cuprous chloride was added as catalyst. 

Nitrophenylarsonic acid has been prepared by heating p-nitrobenzenediazonium chloride with arsenious acid in hydrochloric acid, by the action of -nitrobenzenediazonium chloride on sodium arsenite, by the action of sodium arsenite on sodium -nitrobenzeneisodiazo oxide, by the diazotization of -nitro-aniline in acetic acid in the presence of arsenic chloride and cuprous chloride, and by the reaction of -nitrobenzenediazonium borofluoride with sodium arsenite in the presence of cuprous chloride. ...
