Neue Synthesen durch Aktivierung tertiärer Carbonsäureamide mit Trifluormethansulfonsäureanhydrid

Preserved Fulltext
Treatment of propiolic acid amides with trifluoromethanesulfonic anhydride (Tf2O) leads to the formation of trifluoromethanesulfonyloxy iminium salts. These salts react with a further equivalent propiolic acid amide to bis(iminio)ether salts, which undergo a DDA-reaction. After hydrolysis 1-phenylnaphthalene-2,3-dicarboxamides were isolated in good yields. Treatment of alpha-diazo acetoamides with Tf2O leads to reactive alkenediazonium salts, which undergo an electrophilic aromatic substitution
