Pentafluorobenzoyl and heptafluorobutyryl derivatives of cytosine and pentafluorobenzoyl-5methylcytosine have been examined by mass spectrometry following permethylation. Electron impact mass spectra were used to confirm the structures of the derivatives. The permethylated pentafluorobenzoyl derivat
Gas chromatographic analysis of the products of reaction of diazomethane with tolbutamide and chlorpropamide indicates the formation of three compounds in both cases. As expected, N-methylation (at sulfonamide nitrogen) is the predominant reaction; minor amounts of O-methylated product are also obse
Several procedures involving gas chromatography (CC) have been described for the analysis of phenylurea herbicides. Earlier methods were based cm the hydroiysis af pfienyiureas followed by GC of the correspond&g anilines, either di\_z~.Aly~-~ or as derivatives~-5. The transformation Into &tines has
