DMF is recommended as diluent in the Ullmann synthesis of diaryls from aryl halides and as solvent for the Beckmann rearrangement of steroidal enone oximes. The Willgerodt-Kindler reaction (a carbonyl compound with a secondary amine and sulfur to give a thioamide) can be carried out in good yield at 50-60 if DMF is... [Pg.873]

Treatment of [ C]methyl aryl ketones with thaUium(lll) nitrate in acidic methanol (McKillop rearrangement) or with ammonium polysulfide or sulfur and morpholine at elevated temperatures (Willgerodt-Kindler reaction) provides labeled arylacetic acid derivatives. In the first case the aryl group migrates from the carbonyl position into the former methyl position, so that the label is shifted by one position. For example (Figure 6.12), in the synthesis of [6- / C]porphobilinogen the pyrrole 22 was acetylated with... [Pg.295]
