Abstract

original image

The sterically crowded, highly electron-deficient diazonium salt C6(CF3)5N2+ BF4 has been synthesized and sample dediazotization reactions were carried out. New compounds, C6(CF3)5I, C6(CF3)5NO2, and C6(CF3)5NO were isolated and identified. Also, a more convenient route to C6(CF3)5NH2 that gave good yield was achieved.
