The unique nitration of the carbamate fungicide diethofencarb (Powmyl, isopropyl 3,4-diethoxycarbanilate) was examined in 14 Japanese soils and three types of clays under the aerobic conditions using the 14C-Iabeled compound. Nitration at the 6
The Phthalimidomethyl Rearrangement
Wilshire, John F. K.
, p. 1817 - 1826 (2007/10/02)
The discovery of a new acid-catalysed monodentate N -> C aromatic rearrangement, namely the phthalimidomethyl rearrangement, is reported.In this rearrangement, discovered during the reaction of N-hydroxymethylphthalimide with certain alkyl N-(4-nitrophenyl)carbamates in concentrated sulfuric acid solution, the phthalimidomethyl group migrates from its initial location on the nitrogen atom of the carbamate function to a carbon atom of the nitrophenyl group.Evidence, provided by an appropriate 'crossover' experiment, indicates that the rearrangement is intermolecular.Hindered rotation about the N(carbamoyl)-aryl bond of the N-phthalimidomethyl derivatives of both ethyl and methyl N-(2,4-dinitrophenyl)carbamate is reported.
